Abstract

We propose a reconfigurable broadband mode (de)multi-plexer based on a thermally induced long-period grating integrated with an asymmetric Y -junction. Either of the two spatial modes of a two-mode waveguide launched into the grating end of the device can be switched into either of the two output ports of the Y -junction by controlling the electric power applied to the electrode heater that induces the grating. Our typical device fabricated with polymer material that has a length of ~14 mm shows a mode selectivity higher than 12 dB over the C + L band at a switching power of 198 mW. The device could find applications in reconfigurable mode-division-multiplexing systems.
