ABSTRACT:
An InP-based photonic integrated circuit (PIC) includes an optical passive element in the circuit with no bias current applied to such an element. A passivation cladding layer overlies a surface of the optical passive element where the passivation layer comprises benzocyclobutene polymer or BCB.
