Top contact VCSEL with monitor |
摘要 |
A vertical cavity surface emitting laser (VCSEL) and monitoring diode combination having reduced parasitic capacitance for use in high bandwidth communications systems. The VCSEL has both p-type and n-type contacts on the same face. This allows the VCSEL to be mounted on a monitor chip or diode without using a metal contact layer. In an embodiment wherein the VCSEL is soldered to the monitor chip for mechanical stability only a small metal pad no larger than the VCSEL is used. The reduction in metallisation results in a lower parasitic capacitance that in turn results in higher potential operational speeds
