Abstract

Micromachined tunable VCSELs are particularly useful for wavelength division multiplexing applications because of their large continuous wavelength tuning range without mode-hopping. We have achieved 26 nm single mode continuous wavelength tuning with threshold current density as low as 550 A/cm2. By reverse biasing the laser, we can obtain a tunable resonant cavity photodetector with simulated linewidth less than 2 nm. Narrow linewidth tunable photodetectors are particularly useful in extending the wavelength separation between WDM channels beyond those offered by other techniques.
