Cryogenic measurement of the DC Kerr and two-photon absorption coefficients at 2 µm using silicon p-i-n diode waveguide modulators
{{output}}
Efficiency of nonlinear interactions in silicon photonics at 1.55 µm is usually limited by two-photon absorption, which can be alleviated by moving to longer wavelengths (> 2 µm). Here, we use an integrated p-i-n diode-based waveguide electro-optic modulator... ...
