Photonic switches based on phase change materials and microring resonators
[ANGLÈS] In this work we demonstrate optical switching at telecommunication wavelengths on silicon microring resonators induced by a change between the amorphous and crystalline phases of a thin film of phase change material. The transition is triggered using a pulsed laser diode at 975 nm and the o...

| Sumario: | [ANGLÈS] In this work we demonstrate optical switching at telecommunication wavelengths on silicon microring resonators induced by a change between the amorphous and crystalline phases of a thin film of phase change material. The transition is triggered using a pulsed laser diode at 975 nm and the optical transmission probed with an ASE source between 1520 and 1580 nm. Changes in the quality factor, resonant wavelength and peak depth are investigated as well as the effect of temperature in the performance of the switch. The work may have further applications in optical communications, add-drop multiplexers and reconfigurable photonic circuits. |
