Theory of self-injection locking of a laser diode to a whispering gallery mode microresonator

The key properties of the self-injection locking regime of a laser diode to a high-Q microresonator with whispering gallery mode made of crystalline silicon are considered. It has been experimentally demonstrated the possibility of the self-injection locking using cavity made of crystalline silicon. This result opens up new possibilities for creating narrow-band highly stable laser sources in midIR, over 2.3 microns, on a new hardware base.

Fiber Characterization

Optical fiber characterization using whispering gallery mode resonances of the fiber itself has been demonstrated to be a powerful technique. In this work, we exploit the thermal sensitivity of whispering gallery mode resonances to characterize the pump-induced temperature increment in holmium doped and holmium-ytterbium codoped optical fibers. The technique relies on the measurement of the resonances’ wavelength shift due to temperature variation as a function of the pump power. Holmium doped fibers were pumped to the second excited level 5I6 of the Ho3+ ion using a laser diode at 1125 nm and ytterbium-holmium codoped fibers to the 2F5/2 level of the Yb3+ ion by a laser diode at 975 nm. Our results demonstrate that pumping ytterbium-holmium codoped fibers at 975 nm results in dramatic thermal effects, producing a temperature increment two orders higher than that observed in holmium doped fibers pumped with a 1125 nm laser diode.
