Abstract
A new way to make a star coupler is described, fabricated by stacking polymer films and then sticking them together using a heat press. By this method, star couplers with square core cross sections can be produced easily. The five-port multimode planar star coupler, made on an experimental basis, has an output power variation of ~1 dB and an insertion loss of ~3.5 dB.
