ABSTRACT:
An optical device (300) including first and second facets (340, 350); an at least partially bent waveguide (320) formed on a substrate and including a portion perpendicular to the first facet; and a light amplification region (310) coupled to the bent waveguide. The light amplification region includes an expanding tapered portion and a contracting tapered portion which approaches the second facet.
