Did you know?
WebKerr frequency combs (also known as microresonator frequency combs) are optical frequency combs which are generated from a continuous wave pump laser by the Kerr … Web2 de dez. de 2016 · The Kerr response is intrinsic to the device material, and cavity-based frequency combs leveraging the Kerr nonlinearity have been demonstrated in …
WebFor Kerr frequency combs the typical range is from around 10 GHz to 1 THz. The coherent generation of an optical frequency comb from a continuous wave pump laser is not a unique property of Kerr frequency combs. Optical frequency combs generated with cascaded optical modulators also possess this property. Web2 de dez. de 2016 · This work analyzes the condition under which Kerr combs generate the highest microwave output power after photodetection and demonstrates primary combs with a sidemode-to-pump ratio as high as -2 dB, thereby leading to efficient energy conversion from the lightwave to the microwave frequency range. 11 PDF
