An etched beam splitter (EBS) photonic coupler based on frustrated total internal reflection (FTIR) is designed, fabricated and characterized in the InP/InGaAsP material system. The EBS offers an ultra compact footprint (8x11 μm) and a complete range of bar/cross coupling ratio designs. A novel pre-etching process is developed to achieve sufficient depth of the etched coupling gaps. Fabricated ...

We experimentally study both reshaping of nonreturn-to-zero (NRZ) signal and NRZ to pseudoreturn-tozero (PRZ) format conversion based on self-phase modulation of a semiconductor optical amplifier (SOA) and...

Chaotic secure communication schemes encounter a conflict of key space enhancement between the consistency and complexity chaotic transceivers. In this paper, we propose monolithically integrated multi-section semiconductor laser (MIMSL), used as compact transceiver with an enhanced space. The MIMSL consists distributed feedback (DFB) section, optical amplifier (SOA) two phase (P) sections pass...

We demonstrate simultaneous demultiplexing, data regeneration and clock recovery at 10Gbits/s, using a single semiconductor optical amplifier-based nonlinear-optical loop mirror in a phase-locked loop configuration.

Introduction: Ultra-high capacity optical interconnection networks are considered as a potential solution to the immense processormemory access communications bottleneck, which is expected to dominate high-performance supercomputers [1, 2]. Optical packet switching fabrics have the potential to supply this next-generation technology with the performance characteristics necessary for efficient c...
