Paper Abstract

A microoptical receiver module for very high bitrates was designed and realized. We employed well established silicon technologies for integrating the optical components of the microoptical system. For reducing the optical spot size on the photo diode due to the beam divergence of the transmission fiber a monolithically integrated silicon microlens was used. The microlenses were fabricated by melting of photoresist and transferring the preforms into the silicon substrate. We characterized the lenses by lateral shearing interferometry in transmission. The beam diameter on the photodetector (l/e2) could be reduced by about one order of magnitude to less than 10 micrometers . The sensitivity of the modules was about 0.5 A/W at 1310 nm and 0.6 A/W at 1550 nm.
