Abstract
We have used laser-micromachined alumina substrates to build a three-dimensional photonic
band-gap crystal. The rod-based structure has a three-dimensional full photonic band gap between
90 and 100 GHz. The high resistivity of alumina results in a typical attenuation rate of 15 dB per
unit cell within the band gap. By removing material, we have built defects which can be used as
millimeter-wave cavity structures. The resulting quality ~Q! factors of the millimeter-wave cavity
structures were as high as 1000 with a peak transmission of 10 dB below the incident
signal. © 1995 American Institute of Physics.
