Transmission characteristics of 1.3 /spl mu/m Fabry-Perot laser diodes integrated with spot size converter for 2.5 Gbit/s applications

This article demonstrates the application of highly efficient Fabry-Perot lasers to intra-office STM-16 fiber communication systems at the wavelength of 1.3 /spl mu/m. Low power penalty of 0.05 dB through a 12 ps/nm fiber was measured at 25/spl deg/C and 85/spl deg/C. A low coupling loss of 1 dB of a laser to a cleaved SMF fiber is achieved. This device consists of an active stripe followed by a passive intracavity spot size converter. Subsequently, this paper demonstrates the feasibility of non-perturbing intracavity tapers through the application of selective area growth and their applicability to short haul optical systems.
