Abstract: A Mach Zehnder (MZ) modulator (1) comprising a splitter (4) for splitting incident light in one wave guide (3) into two modulator arms (5,6) of the MZ and comprising a combiner (7) that combines light from the two arms {5,6) into an output mode, where electrodes (9,10) are present in connection with said arms (5,6) for changing the refractive index in said arms in order to modulate incident light so that the light is amplified or so that an extinction, due to interference between the light in the two arms, takes place. The invention is characterised in, that the splitter (4) is arranged to split incident light equally into the two arms (5,6) and in that a part (11) of one of the arms (5) between said electrode (9) and said combiner (7) is designed to cause an intentional loss of light in the wave guide (3), whereby a desired asymmetry in transmission of the two arms (5,6) occurs.

Abstract: A waveguide for the extraction of light at low levels of reflection arranged to guide light from an electro-optical component on a chip to a facet on the chip for extraction. The invention is characterised in that the waveguide comprises a first part and a second part, in that the first part (4) is extended, in that the second part (5) comprises a surface (JK) through which the light exits from the waveguide (1), in that a non-adiabatic longitudinal section (GHLM) is located after the first part (4) but before the said surface (JK) in the direction of propagation of the light, and in that the said surface (JK) forms in the plane of the chip a first angle (Vl) with the optical axis (A) of the first part (4) that lies between 5 and 80 degrees.
