Abstract
A launch quasi-optical amplifier including a photonic bandgap crystal, designed to operate within a specific frequency range. The photonic bandgap crystal is populated with active devices that are coupled to the alternate layers, or defects, in the crystal to compensate for the absorption in the alternate layers thereby creating a negative absorption coefficient. The photonic bandgap crystal is operable as an amplifier when the active devices are amplifiers, and as a wave source when the active devices are oscillators.
