The Finisar BPDV412xR balanced photodetector is a compact module consisting of two 100 GHz waveguide-integrated photodiodes on a single chip. As a single device, this configuration ensures excellent uniformity of the paired photodiodes performance; biasing is achieved via an integrated business network. Due to the optimized design of the waveguide and Photodiode, even at high optical power, a linear frequency response can be guaranteed. The integrated termination allows an excellent match of the electrical output signal. Custom configurations are available, such as BPDV matched pairs and quad sets, including connector customization and fiber matching to enable coherent detection. A 90 GHz version of this module is also available upon request.
