초록
We investigate and demonstrate a 100-Gb/s (4x25-Gb/s) receiver optical subassembly (ROSA) based on avalanche photodiodes and a thin-film filter-based demultiplexer. The overall alignment tolerances of the ROSA are relaxed to have larger than 짹 25 μm by improving optical coupling structure. The receiver sensitivity of each lane is also measured to be less than -22.2 dBm, a record minimum to our knowledge, at the bit error ratio of 10-12 for 25.78-Gb/s NRZ signal.
