Abstract (in Japanese) (See Japanese page) 
(in English) We have investigated monolithically integrated Ge p-i-n photodiodes and Si variable optical attenuators (VOAs). The Ge photodiode exhibits low dark current of 60 nA and high responsivity of 0.85 A/W at -1 V. Si VOA also shows efficient light attenuation, as the injection current increases. Furthermore, the Ge photodiode shows approximately 1 GHz of 3-dB cut-off frequency while fall and rise time of Si VOAs are few nanoseconds. These dynamic properties ensure synchronized operation between Si VOA and Ge photodiode at 100 MHz. Such a device configuration, consisting of a tapping splitter, a Ge photodiode as a monitoring detector, and a Si VOA is useful for a signal equalization application in burst-mode optical communication.
