Photonic band structure of guided block modes in high index films fully etched through with periodic microstructure
Atkin, D.M., Russell, P.St.J., Birks, T.A. and Roberts, P.J. (1996) Photonic band structure of guided block modes in high index films fully etched through with periodic microstructure. Journal of Modern Optics, 43, (5), 1035-1053. (doi:10.1080/09500349608233264).
By adapting the well-known 'zigzag' ray model for use with a periodic waveguide (i.e. replacing the plane wave rays with Bloch wave rays), we show that thin films of high refractive index, supported by a low index substrate and fully etched through with a periodic pattern, can support guided modes. From the dispersion relation of these guided Bloch modes, it is shown that the in-plane modal group velocity can be zero, suggesting applications in enhanced dipole-field interactions and control of spontaneous emission in waveguide lasers.
