“…The InP semiconductor optical amplifier (SOA) provided gain exceeds 25 dB, 10 dB more than in earlier reported 4 × 4 SiPh/InP hybrid integrated optical switch [6]. Further to [8], this paper presents an evaluation of the noise figure (NF), the optical signal-to-noise ratio (OSNR) degradation in the gain block, and the switch energy consumption. The OSNR at the output of the gain block is sufficient for a distortion-free 12.5 Gb/s optical data transmission.…”

“…However, optical switches in SiPh incur substantial insertion loss, while not providing any practical mechanism for its compensation, by virtue of an indirect bandgap semiconductor inherently incapable of inter-band gain. The required gain could be provided off chip by hybrid integration to an external gain block, e.g., in Indium Phosphide (InP)-a direct bandgap semiconductor featuring strong inter-band gain in the spectral range of interest for most optical switch applications [6]- [8]. In a SiPh/InP hybrid optical switch, routing the optical signal from an input port to the desired output port is on the SiPh chip, while the InP gain block provides amplification required for compensation of the insertion loss.…”

We design a lossless 8 × 8 Silicon Photonics (SiPh)/Indium Phosphide (InP) hybrid optical switch. The design consists of an 8-channel InP gain block for coupling to an 8 × 8 thermally tuned Mach-Zehnder interferometer-based Banyan switch in a passive SiPh platform. The gain block is an array of eight 1300 μm-long semiconductor optical amplifiers (SOAs). We experimentally verified the InP gain block while the SiPh chip is accounted by replacing it with a loss component. The SOA in line with the optical signal path provides a net gain larger than 25 dB to compensate for the inherently large insertion loss of the 8 × 8 SiPh optical switch. The total energy consumption of the hybrid optical switch in lossless operation mode is 10.44 pJ/bit at 12.5 Gb/s.
