高速光通信，300G探测和调制！！！

前几天，在网上看到了国外有做300G的高速探测器和调制器，太让人吃惊了！是我听到的最快的。
Modulators and Detectors
One of the ambitious goals of the European IPHOBAC project is the development of millimetre-wave high-power photodiode and modulator modules for communications, security/ radar and instrumentation applications. The activities are well balanced between technological chip fabrication and new package developments. IPHOBAC will provide photodiode and modulator chips & modules for different frequency ranges: broadband (DC-110 GHz), narrow-band (55-65 GHz & 75-110 GHz) as well as wideband (30-300 GHz) operation. Some details are listed below:

Broadband (DC-110 GHz) and high-output power (>0 dBm) photodiode modules using a fi bre-optic package with w1-coaxial output connectors and integrated bias-T. Prototypes are already available!
Narrow-band antenna integrated photomixers for operation at around 60 GHz and WR10 coupled photodiodes for 75-110 GHz operation. Ultra-wideband (30-300 GHz) photomixer modules with integrated planar antennas. The PD chips are mounted in novel fi breoptic packages providing wideband quasioptical millimetre-wave radiation.
Reflective 60 GHz picocell transceivers with integrated optical amplifi er to boost both the received and transmitted optical signals.
Broadband optical transmitter modules for mm-wave signals up to 100 GHz consisting of a high power DFB laser with 1.55 μm wavelength and an integrated ultra-high speed electro-absorption modulator.
