A Ridge Waveguide for Thermo-optic Application
A thermal analysis and structure of a ridge single mode waveguide with a metal heater are presented. The steady-state temperature increases linearly and the thermal response becomes slower at the same power consumption, when the under-etched depth in the lower cladding increases. When the upper cladding thickness decreases, the thermal response becomes faster. This shows that a thinner upper cl...
متن کاملHigh-efficiency native-oxide-passivated high-index-contrast ridge waveguide lasers
A GaAs-based high-index-contrast ridge waveguide laser is fabricated using a self-aligned process of deep dry etching plus oxygen-enhanced wet thermal oxidation of low Al-content AlGaAs. Lasers operating at l1⁄4 813 nm (CW, 300 K) with external differential quantum efficiencies as high as 78% are demonstrated, indicating effective passivation of the directly-oxidised etched active region sidewa...
متن کاملHybrid optical waveguide devices based on polymers and silica
The hybrid integration of polymer and silica in optical waveguides can yield devices that combine the excellent thermo-optic properties of polymers and the superior passive waveguiding properties of silica. The large difference and opposite sign of the thermo-optic coefficients of both classes of materials can be utilized to create athermal waveguide devices. In addition, it can be utilized in ...
متن کاملWaveguide electro-optic modulator in fused silica fabricated by femtosecond laser direct writing and thermal poling.
An integrated electro-optic waveguide modulator is demonstrated in bulk fused silica. A Mach-Zehnder interferometer waveguide structure is fabricated by direct writing with a femtosecond laser followed by thermal poling. A 20 degrees electro-optic phase shift is achieved at an operating wavelength of 1.55 microm with an applied voltage of 400 V and an interaction length of 25.6 mm, which corres...
متن کاملSilica-on-silicon waveguide quantum circuits.
Quantum technologies based on photons will likely require an integrated optics architecture for improved performance, miniaturization, and scalability. We demonstrate high-fidelity silica-on-silicon integrated optical realizations of key quantum photonic circuits, including two-photon quantum interference with a visibility of 94.8 +/- 0.5%; a controlled-NOT gate with an average logical basis fi...
