摘要：

A semiconductor light-to-light transducer has been developed by vertical and direct integration of heterojunction phototransistors and a laser diode. The transducer detects an optical signal and emits an intensified optical output. A linear amplification with gain > 100 for input light of 0-30 muW is achieved by the suppression of internal optical feedback. The static intensity noise properties of the transducer are also investigated theoretically. It is estimated that the noise equivalent power is 30 pW, and the relative intensity noise for a typical input power level of approximately 10 muW is about 10(-14)-10(-13).
