Abstract
An optoelectronic device is provided. A light source emitter and a light source receiver are integrated in the device. The light source emitter is a Zn-diffused vertical cavity surface-emitting laser (VCSEL). The light source receiver is a uni-traveling-carrier photodiode (UTC-PD). With the VCSEL, a 10 Gb/s eye is opened under a small voltage and a small signal amplitude. With the UTC-PD, the 10 Gb/s eye is passed even under zero-bias. Thus, the optoelectronic device has a high speed and power consumption is saved.
