Electrically Tunable Multiquantum-Well InGaAsP-InGaAsP Microphotonic Filter

摘要

Planar waveguide-based Fabry-Perot microcavities of 20- and 40-(mu)m length have been studied. The cavity resonance has been tuned via carrier injection by a maximum of 1.9 nm at a wavelength of 1.3 (mu)m with only 6 mW of tuning power. The interplay between electrical and thermal tuning is highlighted.
