Optical feedback and the coupling problem in semiconductor microdisk lasers
The smaller the size of a light-emitting microcavity, the more important it becomes to understand the effects of the cavity boundary on the optical mode profile. Conventional methods of laser physics, such as the paraxial approximation, become inapplicable in many of the more exotic cavity designs to be discussed here. Cavities in the shape of microdisks, pillars and rings can yield low lasing ...
متن کاملThreshold characteristics of semiconductor microdisk lasers
Whispering-gallery mode microdisk lasers using optical’ and electrical2 excitation have recently been demonstrated. The initial experiments* and results described here use continuous-wave optical excitation at liquid-nitrogen temperatures. The threshold characteristics of these microlasers are studied here as the small volume limit is approached where there is a single optical mode within the g...

متن کاملDirectional light coupling from microdisk lasers
Recently we have investigated the possibility of fabricating optically active microstructures which may potentially be of use in future photonic or optoelectronic circuits. As a first step in this direction we demonstrated the concept of a whispering-gallery mode microdisk laser. ly2 The device makes use of optical modes at the edge of a thin semiconductor dielectric disk which is 2-10 pm in di...
متن کاملMode locking in semiconductor lasers by phase-conjugate optical feedback.
We show theoretically through computer simulations that phase-conjugate optical feedback that is realized through four-wave mixing can produce mode locking in multilongitudinal-mode semiconductor lasers. Phase-conjugate feedback, in contrast to ordinary optical feedback, directly couples pairs of longitudinal modes. For certain strengths of phase-conjugate reflectivities, the phases and beat fr...
