• central region of the microbath. This implies that the beams should be narrow and have a low divergence. To realize this, we chose the single-stripe waveguide of our TripleX waveguiding platform [9]. This is a rectangular Si3N4 ridge waveguide embedded in SiO2 cladding. The TripleX platform offers high

Vernon et al. proposed a compact interferometer design using stripe waveguide coupling to measure the change in the refractive index of a sample using the change in the output intensity [19]. The stripe

• paper, we report the realisation of a refractive index sensor based on stripe waveguide coupling (see Figure 1). The structure is similar to the structure proposed by Vernon et al.

The overall sensor design consists of three identical stripe waveguides labelled as input arm, reference arm and sample arm (Figure 1). The ssb0 mode of

Plasmons were excited using a highly focused 633 nm laser beam and a specially designed grating structure to provide stronger

For a plasmonic stripe waveguide, we demonstrate that QD to waveguide surface distance is a critical factor on the QD PL [11]. We use degree of
