In this Letter, we study theoretically reflectance of a monolayer comprizing regularly spaced quantum Λ-emitters. Due to high density of the latter, the monolayer almost totally reflects the incident field in the vicinity of the system's collective (excitonic) resonance. The emitter self-action through the secondary field provides a positive feedback, interplay of which with the inherent nonlinearity of an emitter itself, results in an exotic behavior of the system reflectance, including bistability, self-oscillations, and chaotic dynamics. All these features might be of interest for nanophotonic applications
