Abstract

A planar lightwave circuit and a method of producing such a planar lightwave circuit, the planar lightwave circuit having an element secured thereon. The planar lightwave circuit comprises: a substrate; a trench cut in the substrate; at least one solder pad deposited on a top surface deposited above the substrate; at least one of a waveguide defined in a layer deposited above the substrate and an optical fiber; and an optical element placed within the trench and in optical communication with the at least one of a waveguide and an optical fiber; at least one metal contact configured on the optical element to be adjacent to the metal pad, the solder pad being connected to the metal contact providing physical support to the optical element and an electrical connection between the metal pad and the metal contact.
