Phys. Rev. Lett. 89, 083902 (2002) [4 pages]Field Quantization for Chaotic Resonators with Overlapping ModesReceived 29 November 2001; revised 21 June 2002; published 31 July 2002 Feshbach’s projector technique is employed to quantize the electromagnetic field in optical resonators with an arbitrary number of escape channels. We find spectrally overlapping resonator modes coupled due to the damping and noise inflicted by the external radiation field. For wave chaotic resonators the mode dynamics is determined by a non-Hermitean random matrix. Upon including an amplifying medium, our dynamics of open-resonator modes may serve as a starting point for a quantum theory of random lasing. © 2002 The American Physical Society URL:
