A fabrication method for providing a semiconductor light-emitting device includes growing a plurality of layers on a semiconductor substrate, including forming a lower cladding layer and an active region for generating lightwaves. A laminated cladding structure is formed on the active region. The laminated...http://www.google.com.tw/patents/US5400354?utm_source=gb-gplus-share專利 US5400354 - Laminated upper cladding structure for a light-emitting device
