Abstract: A method for attaching at least one optical fiber to a chip includes the steps of: providing at least one nanowaveguide of a chip including at least one nanowaveguide end to be attached to at least one off-chip fiber respectively; forming at least one oxide taper over or adjacent to each of the at least one nanowaveguide end; cleaving at least one fiber end; aligning the chip so that an end face of each of the at least one oxide taper is mechanically aligned substantially adjacent to each corresponding cleaved fiber end; and fusing each of the at least one oxide taper with each of the at least one fiber end respectively to modally couple each of the nanowaveguides to each of the at least one fiber end via each of the oxide tapers. A device for attaching at least one optical fiber to a chip is also described.

Abstract: A deposition method for manufacturing an active electro-optic layer includes providing a substrate or a base layer; and applying an electric field across a silicon nitride layer as it is being deposited on the substrate or the base layer to cause a poling of a deposited layer. Alternative methods for poling an active electro-optic layer and an electro-optical device are also described.

Abstract: Photonic devices and methods for operation thereof are disclosed. A photonic device may include a laser configured to generate light. The photonic device may also include a weak value device having a ring resonator. The weak value device may receive the light from the laser and modify the light using the ring resonator to form return light. The photonic device may further include a stabilizing structure configured to generate a tuning signal based on the return light and control one or both of the laser or the ring resonator using the tuning signal to lock a frequency of the laser to a resonance frequency of the ring resonator.

Abstract: A device for attaching at least one optical fiber to a chip includes at least one nanowaveguide disposed on a substrate of a chip to be attached to an at least one off-chip fiber respectively. At least one oxide taper mode converter is disposed around a nanowaveguide end and in optical communication with and modally coupled to each of the at least one nanowaveguide respectively, and adapted such that each corresponding fiber of at least one off-chip fiber corresponds to a cleaved fiber end each cleaved fiber end to be fused to each oxide taper mode converter respectively to optically couple and mode match each cleaved fiber end to each of the nanowaveguide ends of each of the at least one nanowaveguide via the oxide taper mode converter by a modal coupling. A method for attaching at least one optical fiber to a chip is also described.
