- Abstract
- A smart and compact packaging transmitter optical subassembly. (TOSA) in a 10-Gb/s small-form-factor pluggable (XFP) transceiver module has been developed with an eye towards electrical and thermal performances. In the TOSA, a bias-tee circuit and a matching resistor are monolithically integrated on an AIN submount with high thermal conductivity, and a newly proposed coplanar waveguide is drawn in a transistor outline (TO)-stem. In order to improve the electrical performance of the TOSA, the equivalent circuit model of all optoelectronic components in the TOSA is introduced and utilized. The fabricated TOSA shows the -3-dB bandwidth as high as 11 GHz and 0.36-dB penalty after a 75-km transmission at an elevated temperature of 85 degrees C.
