Monolithically integrated optical transceiver chips at 850 nm wavelength consisting of VCSELs and MSM photodiodes

In this paper we report on a transceiver chip that is even suited for bidirectional Gbit/s transmission over a PCS fiber. The monolithic integration of a VCSEL and a metal-semiconductor-metal photodiode (MSM PD) as well as a design avoiding the use of external optics are expected to simultaneously save space, weight and module cost.
