Abstract

We propose a photonic crystal (PhC) nanofishbone (NFB) nanocavity, which confines an ultrahigh Q (∼1.8 × 107) transverse-magnetic (TM) mode. With thin slab thickness and only few PhC periods, the TM mode in NFB nanocavity shows higher Q, larger confinement factor and smaller mode volume than that in PhC nanobeam nanocavity while the total etched-surface area is also significantly reduced. This PhC NFB nanocavity with very compact device size will be very beneficial for quantum cascade lasers, plasmonic nanolasers, and other applications needing high Q TM modes.
