SAF 1093: 1450nm Single Angled Facet Gain Chip
7.1.2.SP.1093 Rev B
Description
COVEGA’s Single Angled Facet (SAF) gain chip is a high-power InP active waveguide gain element. The proprietary SAF design produces low modal reflectance at the angled facet and optimum reflectance at the normal facet. This unique combination of ridge waveguide laser design and broadband low angled facet reflectance makes the SAF ideally suited for use as the gain component in high-power widely tunable external cavity lasers.
Features Applications
Gain medium for widely tunable external cavity semiconductor lasers Gain medium for narrow line-width fiber Bragg Grating Lasers → → → Broad tuning range High Output Power Low Angled Facet Reflectivity
