Combining photonic crystal slab with exciton resonance: New physics and functions

Research output: Contribution to journalConference articlepeer-review


Linear as well as nonlinear optical responses of periodic array of semiconductor in a waveguide structure are reviewed. The period is chosen in the scale of optical wavelength. Such structures can be demonstrated by imbedding an inorganic-organic perovskite compound into quartz grating grooves. By virtue of its large excitonic oscillator strength, strong coupling regime is realized even at room temperature. Polraritonic effect, directional photoluminescence and ultrafast optical switching operation are discussed.
