Abstract
We report on a system to control the emitted wavelength of a laser independently
from its pump conditions. To illustrate the concept, it is applied to III-V
microdisk lasers fabricated on a CMOS pilot line for application to multicolored
optical interconnections. Two different control systems are experimentally
studied. The first one requires two coupling areas between the resonator and
its coupled waveguide while the second solution is based on a photonic crystal
mirror and a single coupling area. In both cases, the independent tuning of
their emission from the pump conditions is demonstrated with a very high compacity.
A controlled multimode emission in microdisk lasers is obtained for the first
time.
