An optical device has a back facet (27) and a front facet (29; 29)
opposite to each other, and includes a laser (23) adapted to emit light
essentially perpendicular to said back facet; a modulator (25; 51; 55) having
an input end and an output end (35; 53; 57), 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 (33) 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 (34), which is angled (;
) with respect to the normal (Z; 71) of said device front facet.
