摘要： A transistor-outline TO-can type optical module includes a stem, a sub-mount arranged in the stem and a laser diode (LD) is mounted in the sub-mount. A photo diode (PD), which has an inclined light incident surface, converts light emitted from the LD to current. A plurality of leads is extended through the stem while electrically being connected to the sub-mount. The inclined light incident surface of the PD permits that sufficient monitoring of photocurrent can be obtained and a p-side up bonding of a p-type electrode is allowed. Thus, the SMSR of the LOB is increased. A bias-tee is built in the TO-can to reduce heat caused by DC current and to increase opto-electric efficiency while suppressing an increase in the temperature of an LD chip.

摘要： Disclosed is an optical receiver for receiving burst mode signals. In a first embodiment, AGC voltage is applied to a continuous mode TIA having an AGC function, so that the AGC function is stopped and a gain of the TIA is fixed to a constant. In a second embodiment, a continuous mode TIA capable of adjusting an AGC time by using an external condenser is used. Accordingly, the TIA commonly used in a continuous mode is utilized in a burst mode operation, so that the construction of the optical receiver can be simplified and cost can be saved.
