Abstract

Highly efficient microoptics mounted on a Si-V-groove in a 4.5-mm-high MiniDIL has been developed for use in a high-speed, long-haul transmitter. The optics consists of a 1.5-mm-diameter 0.55-NA aplanatic aspheric singlet and a 2-mm-diameter microisolator. The coupling from a laser diode to a single mode fiber was 67% in the fiber alignment area of /spl plusmn/275 /spl mu/m.
