A laser threshold condition derived from the instantaneous form of Maxwell's equations is presented. This derivation incorporates the passive quality factor of the resonator and is particularly amenable to semiconductor microcavity lasers. The optical confinement factor is derived and compared to previous reports. The threshold condition derived here is compared to the results of active cavity finite-difference time-domain calculations, and excellent agreement is found.
