“…The coupling technology described here has also been applied to a 40-Gb/s hybrid WGPD-AMP [72] and a 72-GHz WGPD-based stimulus probe head [73]. These devices also demonstrated good efficiency, which indicates that this coupling technology is well-suited to WGPD's.…”

The two main trends in the progress of ultrawideband/high-frequency photodetectors (PD's), improving the bandwidth-efficiency product and obtaining a high saturation current, are reviewed. With respect to achieving large bandwidthefficiency, the limiting factors and potentials of edge-coupled (waveguide, waveguide-fed, traveling-wave, periodic-travelingwave), resonant-cavity, and refracting-facet photodiodes, as well as the avalanche photodiode are discussed. Regarding high-saturation current, the author estimated how much the space-charge effect limits the saturation current and two ways to reduce the space-charge effect are outlined. One way is to distribute the photocarriers along the edge-coupled PD's and the other is to increase the carrier velocity using a uni-traveling carrier structure. The waveguide-photodiode-based technologies that we have developed are also presented; namely the design and fabrication of a 100-GHz waveguide photodiode (WGPD), uni-traveling carrier WGPD, 60-GHz packaging, and a 20-GHz large-core WGPD for the planar lightwave circuit integration. A 50-Gb/s receiver opto-electronic integrated circuit technology based on the WGPD is also presented.

“…The remaining losses are therefore in the 3-5-dB range. We can attribute these losses to two factors, which are: 1) the flip-chip mounting of the photodiode give rise to RF losses because of a mismatch between the characteristic impedances of the photodiode and the gold pads [27] and 2) the distance between the PD and the MMIC is too important, leading to resonance in the frequency range of interest. Further experiments are thus necessary to fully control this new packaging technology.…”

“…Broadband photo receivers achieving high amplification as well as high bandwidth are usually combinations of small photodiodes with low parasitics and distributed amplifiers [1,2]. There have been also efforts to integrate photodiode and amplifier monolithically, resulting in complicated technological processes and sacrificing state of the art photodiode-structures [2,3,4,5,6].…”

Hybrid integrated optical receivers for high-speed data transmission

et al. 2003

Flip-chip-mounting of integrated circuits has been shown as an effective way to connect integrated circuits with substrates providing highest bandwidths. This technique also has been used to connect chips directly without causing significant parasitics. In this paper, hybrid integrated photo receivers with high bandwidth for fiber-optic data transmission will be discussed. Several photo receivers with bandwidths of more than 60 GHz have been fabricated by combining photodiodes and amplifiers, which have been optimised in separated wafer runs. Key features of this type of photo receivers are a wave guide photodiode with a high responsivity (0.8 A/W) and a travelling wave amplifier with low input impedance as well as high amplification to a 50 ohm output termination up to 65 GHz. Further improvement of bandwidth is expected by using metamorphic HEMTs instead of pseudomorphic ones in the amplifier
