Silicon photonic-based refractive index sensors are of great value in the detection gases, biological and chemical substances. Among them, microring resonators most promising due to their compact size narrow Lorentzian-shaped spectrum. The electric field a subwavelength grating waveguide (SWG) is essentially confined low-refractive dielectric, favoring enhanced analyte-photon interactions, which represents higher sensitivity. However, it very challenging further significantly improve...
A highly efficient dual-wavelength ytterbium-doped fiber linear cavity laser is experimentally demonstrated. Two cascaded Bragg gratings are used as the wavelength selection component. Stable dualwavelength operation and wavelength-switching modes can be realized by appropriately adjusting polarization state of intra-cavity light reflectivity cavity. For operation, power difference between two lasers (1029.7 1040.4 nm) less than 0.6 dB signal-to-amplified spontaneous emission (ASE) ratio...
We construct a novel nested linear cavity configuration to generate supercontinuum (SC) under continuous-wave pump. With this structure, stimulated Raman scattering and four-wave mixing can affect the whole region of SC spectrum while pump line is removed outside continuum, symmetrical be obtained. The properties structure are demonstrated by using 3.5-km single-mode fiber, an centered at 1315 nm with bandwith 102 output power 1.3 W achieved. By tuning feedback fiber Bragg grating, we easily...
