چکیده
The velocity-matched distributed photodetectors (VMDP) with high saturation power and large bandwidth have been proposed and demonstrated. The theoretical analysis on the trade-off between saturation power and bandwidth shows that VMDP provides fundamental advantages over conventional photodetectors. The theory for designing and simulating the performance of the VMDP is developed comprehensively from the aspect of microwave transmission line, optical waveguide, and the VMDP structure. The VMDP with very high saturation photocurrent (56 mA) and instrument-limited bandwidth (49 GHz) is demonstrated experimentally. The theoretical analysis and experimental results show that . VMDP is attractive for high-performance microwave photonics links and high-power optical microwave applications.

High Speed Velocity-Matched Distributed Photodetectors
In the last few years, remarkable progress has been made in ultrafast, and high-speed, high power photodetectors, as reviewed in [ 1,2]. In terms of applications, the high-speed photodetectors can be divided into four general different categories: (1) high-speed digital communication systems, (2) RF photonic systems, (3) ultrafast optoelectronic sampling, and (4) optoelectronic generation of mi...

We report on the first demonstration of velocity-matched distributed photodetectors and balanced photodetectors with p-i-n photodetectors. Record-high linear dc photocurrent of 45 mA has been achieved without suffering from thermal damage, thanks to the superior power handling capability of p-i-n photodiodes. A novel fiber alignment technique has been developed to achieve high linear photocurre...

High-power, high-speed photodetectors are the key components for analog fiber-optic links to provide large bandwidth, reduce RF insertion loss, and increase spurious free dynamic range and signal-to-noise ratio [l]. The performance of analog fiber optic links is limited by the maximum linear photocurrent of the photodetector [2]. Conventional high-speed detectors have small absorption volume an...
