Cavity-output-field control via interference effects

Abstract

We show how interference effects are responsible for manipulating the output electromagnetic field of an optical microresonator in the good-cavity limit. The system of interest consists of a moderately strongly pumped two-level emitter embedded in the optical cavity. When an additional weaker laser of the same frequency is pumping the combined system through one of the resonator's mirrors then the output-cavity-electromagnetic field can be almost completely suppressed or enhanced. This is due to the interference among the scattered light by the strongly pumped atom into the cavity mode and the incident weaker laser field. The result applies to photonic crystal environments as well.

Cavity Field Suppression via Interference Effects

Viorel Ciornea, P. Bardetski, Mihai Macovei

The purpose of the study is to show how interference effects are responsible for manipulating the output electromagnetic field of a microresonator in the good-cavity limit. The system of interest consists of a moderately strongly pumped two-level emitter embedded in a photonic crystal microcavity. This is due to the interference among the scattered light by a strongly pumped atom into the cavity mode and an incident cavity weaker laser field. The phase difference of the applied lasers can be a convenient tool to control the photon dynamics. The photon statistics shows super- or sub- Poissonian statistics.

All-optical control of optical frequency combs via quantum interference effects in a single-emitter-microcavity system

Jiahua Li, Rong Yu, Jinyong Ma +1 more

Recent demonstrations of cavity quantum electrodynamics (QED) with a single quantum emitter coupled to an optical microcavity have shown the great potential of this system for engineering the light-matter interaction and developing a wide range of robust quantum devices. Here, we study the creation and all-optical control of optical frequency combs (OFCs) in photon emission from a single-quantum-emitter-microcavity QED system driven with a biharmonic pump light in the presence of a classical control light. We find that, when the strengths and phases of the applied control light are appropriately tuned, enhanced OFC generation can occur by using the parameters of currently existing QED systems. The interference between the biharmonic pump light, which is used to drive the cavity mode, and the light scattered by the two-level emitter into the cavity mode due to the second control light are responsible for the enhancement or suppression of OFCs. We further analyze in detail the influences of the other system parameters including the emitter-cavity coupling strength, the incident pump power, and all kinds of relative frequency detunings on all-optical generation of OFCs. In addition to numerical simulations demonstrating this controlled OFC effect, a complete physical explanation of the underlying mechanism is presented. The presented mechanism can be employed for tailoring and controlling OFCs in a cavity QED architecture.

Interference effects in a photonic crystal cavity

David A. Cardimona, Paul M. Alsing

We investigate quantum interference and classical interference effects when a three-level system interacts with both a cavity field mode and an external driving field mode, within the confines of a photonic crystal material. In freespace, we found that under certain circumstances the cavity field evolves to be equal in magnitude to, but 180° out-of- phase with the external pump field when the pump field frequency equals the cavity frequency. The better the cavity, the quicker this build-up occurs. When the cavity field reaches this out-of-phase condition, the resonance fluorescence from the atom in the cavity goes to zero. This is a purely classical interference effect between the two out-of-phase fields, with the resonance fluorescence going to zero at the same time as the two excited state populations go to zero. This is quite different from the quantum interference that occurs under the right circumstances, when the state populations are coherently driven into a linear combination that is decoupled from any applied field - and population is trapped in the excited states, thus allowing for a population inversion and an amplification of incoming optical signals. In this paper, we investigate the additional effects due to the presence of the altered photon density of states in a photonic crystal.

Interference control of perfect photon absorption in cavity quantum electrodynamics

Liyong Wang, Ke Di, Yifu Zhu +1 more

We propose and analyze a scheme for controlling coherent photon transmission and reflection in a cavity-quantum-electrodynamics (CQED) system consisting of an optical resonator coupled with three-level atoms coherently prepared by a control laser from free space. When the control laser is off and the cavity is excited by two identical light fields from two ends of the cavity, the two input light fields can be completely absorbed by the CQED system and the light energy is converted into the excitation of the polariton states, but no light can escape from the cavity. Two distinct cases of controlling the perfect photon absorption are analyzed: (a) when the control laser is tuned to the atomic resonance and creates electromagnetically induced transparency, the perfect photon absorption is suppressed and the input light fields are nearly completely transmitted through the cavity; (b) when the control laser is tuned to the polariton state resonance and inhibits the polariton state excitation, the perfect photon absorption is again suppressed and the input light fields are nearly completely reflected from the cavity. Thus, the CQED system can act as a perfect absorber or near-perfect transmitter and/or reflector by simply turning the control laser off or on. Such interference control of the coherent photon-atom interaction in the CQED system should be useful for a variety of applications in optical logical devices.

Single-Emitter Laser in a Photonic Band Gap Micro-Chip

Lucia Florescu, Sajeev John

We study a laser consisting of a coherently pumped two-level emitter coupled to both a multimode waveguide channel and a high-quality micro-cavity embedded within a photonic crystal. One mode is engineered to exhibit a sharp cutoff within the PBG, leading to a large discontinuity in the local photon density of states near the atom. Another mode of the waveguide channel is used to propagate the pump beam. The cavity field characteristics are highly distinct from those of a corresponding high-Q cavity in ordinary vacuum. We demonstrate strong enhancement of the cavity field, better coherence, and narrower emission spectrum resulting from the radiation reservoir of the photonic crystal

Interference effects in a cavity for optical amplification

David A. Cardimona, Paul M. Alsing

In space situational awareness scenarios, the objects needed to be characterized and identified are usually quite far away and quite dim. Thus, optical detectors need to be able to sense these very dim optical signals. Quantum interference in a three-level system can lead to amplification of optical signals. If we put a three-level system into a cavity tuned to the frequency of an incoming optical signal, we anticipate the amplification possibilities should be increased proportional to the quality factor of the cavity. Our vision is to utilize quantum dots in photonic crystal cavities, but as a stepping stone we first investigate a simple three-level system in a free-space optical cavity. We investigate quantum interference and classical interference effects when a three-level system interacts with both a cavity field mode and an external driving field mode. We find that under certain circumstances the cavity field evolves to be equal in magnitude to, but 180° out-of-phase with the external pump field when the pump field frequency equals the cavity frequency. At this point the resonance fluorescence from the atom in the cavity goes to zero due to a purely classical interference effect between the two out-of-phase fields. This is quite different from the quantum interference that occurs under the right circumstances, when the state populations are coherently driven into a linear combination that is decoupled from any applied field - and population is trapped in the excited states, thus allowing for a population inversion and an amplification of incoming optical signals.
