| Research Abstract |
We have fabricated HEMT's with a strained InGaAs, whose mole fraction is close to that of InAs, as the channel have been fabricated and characterized high-frequency performances using a network analyser. HEMT's with the gate length of 0.1μm exhibited a current cut-off frequency(fT) research ranging over 200 GHz. We have also fabricated MSM-PD's with a strained InGaAs channel and characterized the optical response using a fiber laser with a bandwidth of 400 femt-seconds. MSM-PD's with a L & S of 0.2/0.6μm exhibited a pulse width less than 20 psec. This is because the strained InGaAs has a relatively high drift velocity of electrons. In addition, these MSM-PD's exhibited a responsivity more than one regardless of the channel width as thin as 10 nm. In this way, ultra-high speed OEIC's can be realized by simultaneously fabricating MSM-PD's and HEMT's on the same epitaxial wafer. Therefore, an application of these MSM-PD's to high-speed OEIC's for use in broad-band optical communication systems is expected.
