Multirange wavelength-selectable microarray light sources simultaneously fabricated on a wafer covering the entire C-Band

Scatterometry measurement of ingaasp/inp grating for DFB lasers grown with MOVPE

“…Stable wavelengths of DFB lasers are also required for wavelength division multiplexing (WDM) network systems [6][7][8]. Furthermore, uncooled, directly modulated DFB-LDS are one of the key devices for 10 GB/s Ethernet and OC-192 applications in recent years [9][10][11][12].…”
