100GHz 高速光电探测器
Description
The FT-DV412xR family contains two photodetector devices, with optimized ultrafast photodiodes with up to 100 GHz bandwidth. Both photodetectors, the FT-DV4120 (f3dB > 90 GHz) and FT-DV4121R (f3dB >100 GHz), are designed with waveguide-integrated photodiodes and show an extremely flat frequency response in power and in phase. The on-chip integrated bias network with optimized RF design in particular, ensures undisturbed frequency response from DC to the 3 dB cut-off frequency and saves costs for internal bias-tees. The devices are especially developed for optimal RF performance revealing virtually no pulse response ringing.
Both photodetectors are characterized in the frequency domain by using a heterodyne technique. In the time domain, a femtosecond pulse source and a 65 GHz sampling oscilloscope are used to measure the pulse response.

100 GHz 超高速平衡光电探测器
The F-tone Netwoeks 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 FT-PDV 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.
