Abstract
Semiconductor photonic device surfaces are covered with a dielectric or a metal protective layer. The protective layer covers the entire device, including regions near facets at active regions, to prevent bare or unprotected semiconductor regions, thereby to form a very high reliability etched facet photonic device.
