Optical buffer with higher delay-bandwidth product in a two-ring system

Landobasa Y. M. Tobing, Mee Koy Chin

We propose a new scheme for buffering optical signals in two-ring resonator system that has a larger delay-bandwidth product than those achievable in single-ring and two-ring configurations of the optical analog of electromagnetically-induced transparency (EIT).

Capabilities and Limitations of Slow Light Optical Buffers: Searching for the Killer Application

R.S. Tucker

We provide an overview of the capabilities and limitations of slow light optical buffers. A number of fundamental waveguide properties such as loss and dispersion severely limit the opportunities for practical slow light optical buffering.

Variable optical buffer using slow light in semiconductor nanostructures

We proposed a compact variable all-optical buffer using slow-light in semiconductor nanostructures. We discuss the general design principle via dispersion engineering. The buffering effect is achieved by slowing down the optical signal using an external control light source to vary the dispersion characteristic of the medium via electromagnetically induced transparency effect. We demonstrate that the semiconductor quantum dot structures can be used as a slow-light medium. In such structure, the total buffering time is variable and controlled by an external pump laser. We present a theoretical investigation of the criteria for achieving slow light in semiconductor quantum dots. New pump scheme is proposed to overcome the sample nonuniformity. Finally, optical signal propagation through the semiconductor optical buffer is presented to demonstrate the feasibility for practical applications.We proposed a compact variable all-optical buffer using slow-light in semiconductor nanostructures.

A compact variable all-optical buffer using semiconductor quantum dot (QD) structures is proposed and analyzed. The buffering effect is achieved by slowing down the optical signal using an external control light source to vary the dispersion characteristic of the medium via an electromagnetically induced transparency effect. We present a theoretical investigation of the criteria for achieving slow light in semiconductor QDs. A QD structure in the presence of strain is analyzed with the inclusion of polarization-dependent intersubband dipole selection rules. Experimental methods to synthesize and the measurements of coherent properties in state-of-the-art QDs are surveyed. Slow-light effects in uniform and nonuniform QDs are compared. Finally, optical signal propagation through the semiconductor optical buffer is presented to demonstrate the feasibility for practical applications.A compact variable all-optical buffer using semiconductor quantum dot (QD) structures is proposed and analyzed.
