Fabricating lasers using polymeric gain media and
resonators is attractive due to the relative ease of
processing polymers compared to inorganic
semiconductors, but manufacturing the microstructures
needed has been challenging. In collaboration with Ken
Singer’s group of CWRU’s Physics Department and the
group of Profs. Eric Baer and Anne Hiltner, we
fabricated a surface-emitting distributed Bragg
reflector (DBR) laser that has a compression moulded
gain medium and a co-extruded resonator. The approach
could allow mass production of polymer lasers by rapid
roll-to-roll methods.
