Balanced Photodetector BPDV2020R
Feb 2004Finisar Corp.Request Info
The BPDV contains two waveguide-photodetectors situated on a single chip. They are on-chip connected as a balanced detector. This configuration ensures an excellent uniformity of the paired photodetectors. The waveguide approach guarantees a linear frequency response in power as well as in phase even at very high optical powers. Consequently, the pulse response shows almost no ringing and is mainly limited by today's best sampling scopes. The photodetectors are biased via the integrated biasing networks with one positive and one negative voltage. The integrated 50-Ohm termination provides an excellent matching of the electrical output signal. Alternative configurations without termination resistors are available on request.
