“Möbius” microring resonator [PDF]
Applied Physics Letters, 2019 A category of optical microring resonator, which is analogous to the Möbius strip, is proposed. The “Möbius” microring resonator allows the conversion between modes with different polarizations in the ring, and light must circulate two cycles to be converted back to the original polarization status, which is similar to a Möbius strip.

Optical isolation using microring modulators
Optics Letters, 2021 Optical isolators, while commonplace in bulk and fiber optical systems, remain a key missing component in integrated photonics. Isolation using magneto-optic materials has been difficult to integrate into complementary metal–oxide–semiconductor (CMOS) fabrication platforms, motivating the use of other paths to effective non-reciprocity such as temporal

Supersymmetric microring laser arrays [PDF]
Photonics Research, 2019 Coherent combination of emission power from an array of coupled semiconductor lasers operating on the same chip is of fundamental and technological importance. In general, the nonlinear competition among the array supermodes can entail incoherence and spectral broadening, leading to spatiotemporally unstable and multimode emission pattern and thus poor

Adiabatic microring modulators
Optics Express, 2012 In this work, we demonstrate and experimentally characterize a new class of high-performance silicon photonic modulators-the adiabatic microring modulator. The adiabatic microring modulator utilizes a vertical PN junction and interior electrical contacts, leveraging all the advantages of previously-demonstrated microdisk modulators.

Modular microring laser cavity sensor
Optics Express, 2021 We propose and experimentally demonstrate a modular microring laser (MML) cavity for sensing applications. The proposed MML permits much more design freedom compared with a traditional simple ring cavity by decoupling the performance parameters into several regions in the cavity.

PT-symmetric microring laser-absorber [PDF]
Optics Letters, 2014 The lasing and coherent perfect absorption (CPA) properties of PT-symmetric microrings with mixed index and gain gratings, externally coupled to a bus waveguide, are theoretically investigated. For a complex grating at the PT-symmetry breaking point, perfect unidirectional (either clockwise or counterclockwise) laser emission can be realized, but the ...

Electrificación por microrredes en zonas rurales de la provincia del Azuay, Ecuador
Memoria Investigaciones en Ingeniería, 2022 La electrificación de zonas rurales es un tema cada vez más relevante, debido a que en ciertos casos no se dispone de la red eléctrica tradicional. Es por ello, que es motivo de estudio el uso de microrredes de energías renovables aplicadas a estas ...

Cascadable excitability in microrings
Optics Express, 2012 To emulate a spiking neuron, a photonic component needs to be excitable. In this paper, we theoretically simulate and experimentally demonstrate cascadable excitability near a self-pulsation regime in high-Q-factor silicon-on-insulator microrings. For the theoretical study we use Coupled Mode Theory.
