Abstract: A transmitter for fiber optical communication is realized using hybrid integration technology.The laser diode and the chip of the laser diode driver and the 4∶1 multiplexer,which are realized in different materials and processes,are fabricated on one same ceramic substrate using a film circuit to make up one opto-electronic integrated circuit,i.e.,an OEIC.The chip and the diode are realized with a 0.35μm CMOS process and with wet etching,polymer planar, and lift-off technologies, respectively.The module is encapsulated with a wing shell.Some parameters of the transmitter are summed as follows:bit rate:2.5GB/s,wave length:1550nm,output optical power:5.5dBm,extraction ratio:9.4dB.
