Paper Abstract

We introduce a class of unidirectional lasing modes associated with the frozen mode regime of non-reciprocal slow-wave structures.1 Such asymmetric modes can only exist in cavities with broken time-reversal and space inversion symmetries. The lasing frequency coincides with a spectral stationary inflection point of the underlying passive structure and it is virtually independent of the size of the cavity. These unidirectional lasers can be indispensable components of photonic integrated circuitry.
