Finisar 50 GHz XPDV Photodetector High Bandwidth U2T XPDV2120RA

OVERVIEW

The XPDV photodetector consists of a well-established, waveguideintegrated

single photodiode chip. Designed to exhibit an optimized

frequency response in both, power and phase. Due to experienced RF

packaging, the pulse response shows almost no ringing. Our integrated

on-chip spot size converter leads to a high responsivity and ensures reliability

and robustness of the XPDV. An advantage of the waveguide structure is the

unsurpassed high-power behavior with linear response up to an optical input

power of 10 dBm. For short pulses, an output voltage swing of more than 1

Vpp can be achieved without any degradation of the pulse response. XPDVs

contain a unique on-chip integrated bias network and ensures undisturbed

frequency response from DC to the 3 dB cut-off frequency.
