Strong modification of light emission from a dye monolayer via Bloch surface waves.
We observe a strong modification of the emission properties of a rhodamine monolayer bonded to the surface of a 1D Si(1-x)N(x):H PhC. The photoluminescence signal observed at 670 nm is enhanced by more than 1 order of magnitude at the angle where the emitters are evanescently coupled to a Bloch surface wave supported by the structure. These results may be important for the design of efficient light-emitting devices and of optical sensors.
