Abstract
Provided is a semiconductor light device comprising a semiconductor substrate having a first conduction type; a first cladding layer having the first conduction type deposited above the semiconductor substrate; an active layer; a second cladding layer having a second conduction type; and a contact layer. The active layer includes a window portion that is disordered via diffusion of vacancies and a non-window portion having less disordering than the window portion, and the contact layer includes a first region and a second region that is below the first region and has greater affinity for hydrogen than the first region.
