Abstract
We report the firstchirped multimode interference-based phased-array ( MMI-PHASAR) for application in multiwavelength lasers (MWL's), To avoi d wavelength ambiguity in MWL's, undesired orders are suppressed by ch irping the array of arms in the demultiplexer. Simulations show that a suppression of adjacent orders of more than 2 dB can be achieved. A 1 x 5 MMI-PHASAR has been realized in which the effect of the chirping is clearly visible according to the simulations.
