Abstract
This invention provides ultra-low noise lasers with exceptional performance through the use of ultra-low loss microresonator based filters/reflectors including multiple (≧3) microresonator rings with different ring radii. The ultra-low loss microresonators provide a long effective laser cavity length enabling very narrow linewidth laser operation, with multiple (≧3) microresonators providing extremely high selectivity of the lasing mode over a very wide wavelength range; supporting single wavelength and widely tunable wavelength laser operation. The highly selective and also low loss filter/reflector supports high output power operation of the lasers.
