Asymmetric waveguide electroabsorption-modulated laser |
摘要 |
A modulated laser device comprising two or more vertically stacked asymmetric waveguides is provided. The laser device comprises a first waveguide having a gain region formed therein for amplifying at least a first mode of light, and a second waveguide vertically coupled to the first waveguide and having a modulator formed therein for modulating a second mode of light having an effective index of refraction different from the first mode. Light propagating in the first waveguide is transferred into the second waveguide via a lateral taper in the first waveguide. The laser device may further comprise a third waveguide positioned between the first and second waveguide for providing isolation between the gain region and modulator. Distributed bragg reflector (DBR) and distributed feedback (DFB) laser designs may be employed in the device.
