Abstract
AlGaInN laser diode technology is of considerable interest for telecom applications and next generation atomic optical clocks based on Sr (by using 422nm & 461nm) and Rb at 420.2nm.Very narrow linewidths (<1MHz) are required for such applications. We report lateral gratings on AlGaInN ridge waveguide laser diodes to achieve a single wavelength device with a good side mode suppression ratio (SMSR) that is suitable for atomic clock and telecom applications.
Highlights
Laser diodes fabricated from the AlGaInN material system is an emerging technology for generation telecommunication systems and optical clocksbased on Sr and a blue cooling transition for Rubidium (Rb) [4p65s2S1/2 4p66p2P3/2] at 420.2nm.A requirement for both of these applications is the need for a single longitudinal optical mode, with a very narrow linewidth (
