Stokes-vector modulation formats are gaining increasing interest for next-generation high-speed optical communication networks. We propose and demonstrate potentially low-cost monolithically integrated InP/InGaAsP waveguide-based Stokes vector analyzer to retrieve the state-of-polarization without using coherent detection.
Optical buffering has been one of the major technical challenges in realizing optical packet switching (OPS) routers. While fiber-delay-line-based (FDL) buffers are the most practical and realistic solution to offer useful amount of capacity, the bulkiness of long FDLs and optical switches has been the main obstacle to practical implementation. This paper demonstrates a compact optical buffer with...
A photonic integrated circuit capable of 1×100 switching is reported. The switch, incorporating more than 250 photonic components along with numerous passive waveguides and bends, demonstrates power penalty <; 1 dB at 10 Gbps and extinction ratio > 50 dB.
We propose and experimentally demonstrate a novel structure for monolithically integrating a TM-mode waveguide optical isolator with active InP devices. A semiconductor ring laser with integrated isolator is fabricated and demonstrated for the first time.
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.
