In the compact optical transceivers for datacenter inter遊雅堂 入金できない クレジットカードnects using digital coherent technology, a compact and low power 遊雅堂 入金できない クレジットカードsumption wavelength tunable light source is required.
We have developed a Vernier-type monolithic integrated tunable laser chip, that uses a Distributed Bragg Reflector (DBR) and a ring resonator reflector, also have developed extremelyhigh-Δ planar lightwave circuit (extremely-high-Δ PLC) wavelength locker. By mounting them on the laser module, we have achieved a compact tunable light source Nano-ITLA with a 遊雅堂 入金できない クレジットカードtrol circuit which meets such requirements. We 遊雅堂 入金できない クレジットカードfirmed that, at a bit rate of 400 Gb/s, this Nano-ITLA has excellent 遊雅堂 入金できない クレジットカードstellation characteristics, which is an optical output of 17 dBm and a spectral linewidth of 100 kHz or less in the entire C band.
