Notes:
Photonic band gap waveguide microcavities were designed, fabricated, and measured in a high-dielectric-contrast GaAs/AlxOy III–V compound semiconductor structure. The photonic crystal is defined by a regularly spaced one-dimensional array of holes in the waveguide. By controlling the spacing between the two central holes, the microcavity is formed. The waveguide microcavity is suspended in the airbridge geometry to further increase optical confinement. Resonance states with cavity quality factors as high as 360 were measured at wavelengths near 1.55 μm, with modal volumes as small as 0.026 μm3. © 2000 American Institute of Physics.
