The cavity enhanced absorption technique is applied to N2O detection around 2.86 μm using a continuouswave color center laser. A high-finesse triangular ring cavity is used in this technology. Transmission through the cavity is obtained by jittering the c
Phonon-polaritons offer an exciting avenue in nanophotonics. We comment on the novel nanofabrication approach presented by Bo Qiang et al. in this issue of Advanced Photonics. Their approach to phononic material allows better radiation manipulation
