Polarization multistability of cavity polaritons.
New effects of polarization multistability and polarization hysteresis in a coherently driven polariton system in a semiconductor microcavity are predicted and theoretically analyzed. The multistability arises due to polarization-dependent polariton-polariton interactions and can be revealed in polarization resolved photoluminescence experiments. The pumping power required to observe this effec...
متن کاملOptomechanics with cavity polaritons: dissipative coupling and unconventional bistability.
We study a hybrid system formed from an optomechanical resonator and a cavity mode strongly coupled to an excitonic transition inside a quantum well. We show that due to the mixing of cavity photon and exciton states, the emergent quasiparticles-polaritons-possess coupling to the mechanical mode of both a dispersive and dissipative nature. We calculate the occupancies of polariton modes and rev...
متن کاملStimulated scattering and lasing of intersubband cavity polaritons.
We present a microscopic theory describing the stimulated scattering of intersubband polariton excitations in a microcavity-embedded two-dimensional electron gas. In particular, we consider the polariton scattering induced by the interaction with longitudinal optical phonons. Our theory demonstrates the possibility of final-state stimulation for the scattering of such composite excitations, acc...
متن کاملHigh temperature cavity polaritons in epitaxial Er2O3 on silicon
On-chip optical interconnects with wavelength division multiplexing are being pursued as a low-power low-latency high-bandwidth alternative to metal interconnects. Significant research has focused on integrating optical gain material into the Si platform, with III-V wafer bonding to Si being the most successful candidate to date. In addition there is a long history of efforts to incorporate Er3...
متن کاملTopological polaritons in a quantum spin Hall cavity
We study the topological structure of matter-light excitations, so-called polaritons, in a quantum spin Hall insulator coupled to photonic cavity modes. We identify a topological invariant in the presence of time reversal (TR) symmetry, and demonstrate the existence of a TR-invariant topological phase. We find protected helical edge states with energies below the lower polariton branch and char...
