Optical resonances of a metallically coated wave-chaotic microcavity are investigated. Mode resonances with a low-contrast quality factor and distinct field patterns are demonstrated. Unlike the resonances in the dielectric chaotic-wave cavity where the refractive escape leads a high optical loss, the resonances in metallically coated cavity hold high quality factors with a low loss induced by metal dissipation. As a potential application, the metallically coated chaotic-wave microcavity could be used for a semiconductor laser source with dense modes lasing and accordingly a low spatial coherent emission.
