Classification: CPC G | IPC G

Claim 17:
18. A waveguide module produced by a method comprising the steps of:
providing an optically transparent substrate having first and second substantially planar parallel surfaces and comprising one or more cells in a predetermined first arrangement;
singulating the optically transparent substrate to produce one or more singulated cells, wherein the one or more singulated cells are separated from the substrate to form one or more singulated cells free from other cells or the substrate;
immersing the one or more singulated cells in a strengthening agent to produce one or more treated cells, wherein the surfaces of each singulated cell of the one or more treated cells is treated with the strengthening agent;
releasably laminating the one or more treated cells to predetermined sites on a surface of a carrier substrate to provide one or more laminated cells, wherein the predetermined sites correspond to the first arrangement;
processing the one or more laminated cells;
delaminating the one or more laminated cells from the carrier substrate to provide one or more delaminated processed cells; and
performing secondary processing of the one or more delaminated processed cells to provide a waveguide module.
