Since the semiconductor laser has unique features of high gain, low facet reflectivity, and amplitude-phase coupling through the α parameter, it is also sensitive to optical injection from a different laser. 95 025802 View the article online for updates and enhancements. trailer << /Size 97 /Info 64 0 R /Root 67 0 R /Prev 328843 /ID[<2afa61044ea933ae7daa123310d9be70>] >> startxref 0 %%EOF 67 0 obj << /Type /Catalog /Pages 63 0 R /Metadata 65 0 R /PageLabels 62 0 R >> endobj 95 0 obj << /S 359 /L 502 /Filter /FlateDecode /Length 96 0 R >> stream �0D���c�€�$��,�qw��yቶ� 0000003985 00000 n The junction shown is few micrometers thick. This laser demonstrated an internal efficiency of 150% and a measured external modulation efficiency of 99.3%. : 3 Laser diodes can directly convert electrical energy into light. We report on directional mode switching in semiconductor ring lasers through optical injection co-propagating with the lasing mode. Tsang. Our simple analytical expression is in good agreement with direct numerical simulations of the full-model equations and can be considered as an analog of the formula estimating the locking range width in a cw laser subjected to a coherent optical injection [5]. �#��i�3#�./5��x�i��kX����Nf!�G��v ߠ��~!��k�Ukb;����"�QV!������;� Since the semiconductor laser has unique features of high gain, low facet reflectivity, and amplitude-phase coupling through the α parameter, it is also sensitive to optical injection from a different laser. 0000006469 00000 n 0000059447 00000 n "� �1�w� ��Z�0 0000006897 00000 n 0000043433 00000 n 2. startxref A laser diode, (LD), injection laser diode (ILD), or diode laser is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing conditions at the diode's junction.
