Abstract:
1. A planar lightwave circuit device, comprising: a planar lightwave circuit (PLC) chip including a first waveguide having a core for guiding a first optical signal along a first axis; a first reflector chip for mounting on the planar lightwave circuit chip, the first reflector chip having a recess for receiving an end of the first waveguide; a first notch formed in the first reflector chip having a planar surface at an acute angle to the first axis for redirecting the first optical signal between the core of the first waveguide and a top surface of the first reflector chip; a first active component mounted on the top surface of the first reflector chip for receiving the first optical signal from the core of the first waveguide or for generating the first optical signal for transmission to the core of the first waveguide; and a first pit in the PLC chip partially surrounding the end of the first waveguide for receiving the first reflector chip.
