Optical Bistability in a Traveling-Wave SOA Connected to a DFB Laser Diode: Theory and Experiment

Abstract

We investigate the bistable response of a traveling-wave semiconductor optical amplifier (SOA) connected bidirectionally to a distributed feedback (DFB) laser diode. By contrast to dispersive DFB amplifiers, bistability is possible for a broad wavelength range of the injected optical signal. A theoretical analysis clarifies the origin of the phenomenon and the conditions under which it occurs. Numerical simulations and experimental results confirm the theoretical analysis. Experimentally obtained step heights up to 25 dB and widths of the bistability domain of 1-4 dB have been found

Optical bistability in distributed feedback semiconductor laser amplifiers

M.J. Adams, Richard R. Wyatt

New theoretical and experimental results are presented for optical bistability in distributed feedback amplifiers at 1.5 μm. The onset of bistability occurs at input powers as low as 1 μW, a factor of about 1000 times less than the input predicted for passive DFB structures. The transient response exhibits a large spike as the amplifier goes through a resonance, in good agreement with the theoretical prediction.

We have demonstrated a broad-band all-optical flip-flop for wavelength-division-multiplexing system based on optical bistability in a semiconductor optical amplifier (SOA)/distributed feedback (DFB)-SOA with wide gain bandwidth for both SOA and DFB-SOA regions. Input signal with two different wavelength selections of 1530.45 and 1578.12 nm and the repetition ration of about 6 ns is injected into the SOA/DFB-SOA.

Optical bistability in active distributed—feedback structures: an experimental and theoretical study

Richard R. Wyatt, Mike J. Adams

Optical bistability in active semiconductor devices has attracted considerable interest recently due to the possibility of combining microwatt switching powers with nanosecond switching times. We present experimental and theoretical results of optical bistability in a distributed-feedback (DFB) laser amplifier operating in reflection at 1.5 μm; switch-on delay followed by a sharp transient overshoot is predicted and observed. Minimum switching energies are in the femtojoule region.

Optical Bistability Behavior in a Distributed Coupling Coefficient Nonuniform DFB Semiconductor Laser Amplifier

Mohammad Saeed Tahvili, Mohammad Hossein Sheikhi

In this paper, a distributed feedback (DFB) semiconductor laser amplifier (SLA) with nonuniform grating is studied for optical bistability behavior. The investigation is focused on distributed coupling coefficient (DCC) structures which have a corrugation with nonuniform depth along the cavity. A modified implementation of transfer-matrix method is used to take gain saturation and coupling coefficient variation along the DCC DFB structure into account. Wavelength dependence of optical bistability and the effect of gain-tuning in DCC DFB SLA's are demonstrated.

Optical bistability in diode-laser amplifiers and injection-locked laser diodes

Rongqing Hui, Sergio Benedetto, Ivo Montrosset

Static and dynamic properties of dispersive optical bistability (OB) in semiconductor lasers biased from below to above threshold have been investigated theoretically. The OB result is found to be varied continuously from below to above threshold with its maximum value located just above threshold; this result has been verified experimentally. A much faster switch-off of OB can be expected when the laser operates in the injection-locked condition.
