Wavelength-adaptable optical phased array in SiO2-Si

Wavelength-adaptable optical phased array in SiO2-Si

An optical phased array in the silica-on-silicon material system (SiO 2 -Si) with 8-nm channel spacing in the 1.5-μm wavelength region is reported. The device exhibits quasi-polarization independent operation with insertion losses of 2.5-3 dB and crosstalk attenuations of >20 dB. It can be adapte...

Zusammenfassung:An optical phased array in the silica-on-silicon material system (SiO 2 -Si) with 8-nm channel spacing in the 1.5-μm wavelength region is reported. The device exhibits quasi-polarization independent operation with insertion losses of 2.5-3 dB and crosstalk attenuations of >20 dB. It can be adapted to the specified center wavelength simultaneously with the adjustment of the input fiber.
