43 GHz BALANCED PHOTODETECTOR Optical Communications
BPDV21x0R

The BPDV21x0R consists of two optimized 43 GHz waveguide-integrated photodiodes on a single chip that show an extremely flat frequency response, both in power and in phase. Coherent’s on-chip integrated bias network with an optimized RF design ensures an undisturbed frequency response from DC to the 3 dB cut-off frequency and saves costs for an external bias tee. The hermetic module is especially designed for use in the optical window at 1550 nm and optimal RF performance. The pulse response reveals virtually no ringing. It is best suited for test and measurement or microwave photonics applications up to 35 GHz. A further advantage of the waveguide structure is the unbeatable high-power behavior. The photodetector shows a linear response up to an optical input power of 10 dBm. Tailored configurations are available, such as BPDV dual pair and quad sets, including connector customization and fiber-matching to enable coherent detection.
