C. Duchet et al., POLARIZATION-INSENSITIVE MODULATOR AND INFLUENCE OF PROPAGATION DIRECTION ON BULK ELECTROABSORPTION, Electronics Letters, 33(3), 1997, pp. 233-235
The authors report measurements on electroabsorption in deep ridge wav
eguide structures. The polarisation sensitivity is found to depend not
only on the detuning but also on the propagation direction. In an InG
aAsP/InP double heterostructure, polarisation insensitivity is obtaine
d over a large detuning range (80nm) for propagation along the [-110]
direction.
