We fabricate and demonstrate all-optical packet switching using a single photonic integrated circuit (PIC), which is constructed from monolithically integrated all-optical flip-flop and switch. Both 10 and 40-Gb/s signal can be transmitted through the PIC.
We fabricate and demonstrate all-optical flip-flop based on novel Mach-Zehnder interferometer bistable laser structure. The MZI-BLD successfully improves falling time to 68ps, switching pulse energy to 67pJ, and threshold current, owing to large modes overlap.
<para> We demonstrate a polarization-insensitive all-optical flip-flop based on a multimode-interference bistable laser diode. Polarization-insensitive flip-flop operation is demonstrated with the set power as low as 3 dBm, by applying 0.3% tensile strain to the multiple quantum wells gain medium. The output state of polarization is stabilized to the transverse-magnetic mode irrespective of...
