Carrier injection-based digital optical switch with reconfigurable output waveguide arms

A compact 1 × 2 waveguide digital optical switch (DOS) with electrically reconfigurable output waveguide arms is proposed and demonstrated. Calculations show that this switch can be much shorter and consume less power than previous DOS designs. An InGaAsP-InP waveguide device based on carrier inject...

Description
Summary:A compact 1 × 2 waveguide digital optical switch (DOS) with electrically reconfigurable output waveguide arms is proposed and demonstrated. Calculations show that this switch can be much shorter and consume less power than previous DOS designs. An InGaAsP-InP waveguide device based on carrier injection was designed and fabricated and exhibits a 20-dB switching contrast ratio. The device length is 1400 μm.
