A novel velocity-matched distributed photodetector (VMDP) is proposed to simultaneously achieve high saturation photocurrent and broad bandwidth. Theoretical analysis on the tradeoff between saturation power and bandwidth shows that the VMDP offers f

A high-power, high-bandwidth photodetector is experimentally demonstrated using a novel velocity-matched distributed photodetector (VMDP). The distributed photodetector structure can achieve large absorption volume and high-saturation power while mai

The IMD3 of a p-i-n waveguide photodiode is characterized up to 18 GHz. The observed frequency dependence of the IP3 closely agrees with that obtained from an equivalent circuit analysis of the photodiode.

High power, high frequency photodetectors are the key components for high performance RF fiber optic links and coherent receivers with high LO power. Conventional high speed photodetectors have poor saturation power because of their small absorption

We proposed a velocity-matched distributed photodetector (VMDP) to achieve high saturation power and large bandwidth. The VMDP with 56 mA saturation photocurrent and an instrument-limited 3-dB bandwidth of 49 GHz is demonstrated.

Improved performance of InP-based long wavelength velocity-matched distributed photodetector (VMDP) with metal-semiconductor-metal photodiodes is experimentally demonstrated. A 3-dB bandwidth of 13 GHz and an external quantum efficiency of 0.57 A/W h

A process technology for direct-coupled FET logic (DCFL) circuits on InP substrates, based on enhancement-mode InGaAs/InAlAs heterostructure-insulated-gate FETs (HIGFETs) is discussed. Its performance was demonstrated by fabricating 11- and 19-stage

Wavelength division multiplexed systems place stringent requirements on the absolute wavelength and wavelength spacing of the elements in laser arrays. Ridge waveguides (RW) show excellent potential for practical implementation due to their simple fa
