  • A “membrane-in-the-middle” optomechanical system is demonstrated using a silicon nitride membrane patterned as a subwavelength grating. The grating has a reflectivity of over 99.8 %, effectively creating two sub-cavities, with free spectral ranges of 6 GHz, optically coupled via photon tunneling. Measurements of the transmission and reflection spectra show an avoided crossing where the two sub-cavities simultaneously come into resonance, with a frequency splitting of 54 MHz. Expressions for the… CONTINUE READING
