Abstract
An optical device has a back facet () and a front facet (') opposite to each other, and includes a laser () adapted to emit light essentially perpendicular to said back facet; a modulator () having an input end and an output end (), respectively, and adapted to receive and modulate light emitted from said laser and to output modulated light at said modulator output end; and a window region () arranged between said modulator output end and said device front facet, said device being further arranged such that modulated light output from said modulator is transmitted through said window region and is output from said device through said device front facet. The modulator is bent such that the modulated light output from said modulator is propagating essentially in a direction (), which is angled (α; δ) with respect to the normal (Z;) of said device front facet.
