Coherent Anti-Stokes Raman Scattering Microscopy by Dispersive Wave Generations in a Polarization Maintaining Photonic Crystal Fiber

Abstract

Abstract-The polarization maintaining photonic crystal fiber (PM-PCF) with two zero dispersion wavelengths is designed and fabricated by the improved stack-and-draw technology in our laboratory. The broadband blue-shifted and red-shifted dispersive waves (DWs) are efficiently generated from soliton self-frequency shift (SSFS) along the slow axis of PM-PCF. By optimizing the pump parameters and the fiber length, the polarized DWs centered in the normal dispersion region can be used as the pump and Stokes pulses for the high resolution coherent anti-Stokes Raman scattering (CARS) microscopy. Moreover, it is demonstrated that the widely tunable relevant CARS wavelengths can be obtained by adjusting the pump wavelength. The CARS microscopy based on DWs can find important applications in detecting the biological and chemical samples with the C

Highly Efficient Tunable Dispersive Wave in a Tellurite Microstructured Optical Fiber

“…For the highly efficient DW, two conditions must be satisfied: Solitons and DW must share the same phase velocity, and the spectral tails of the soliton must overlap with the DW wavelength [11]- [13]. Although some reports have demonstrated the highly efficient DW in MOFs [14]- [19], the reported maximal conversion efficiency ðÞ was limited at $50% [11], and most of the research was based on silica fibers.…”

Intermodal and cross-polarization four-wave mixing in large-core hybrid photonic crystal fibers

“…Fiber modes near the PBG edges are strongly affected by waveguide dispersion, thus the PBG effect can be used to tailor fiber dispersion, even in LMA fibers. Birefringence-assisted FWM in polarization maintaining (PM) PCFs has also been investigated [7][8][9]. Phase matching relies on the different phase velocities of the waves propagating in the two polarization modes of a PM PCF.…”

Polarization switch of four-wave mixing in large mode area hybrid photonic crystal fibers

“…Phase matching through the PBG effect in LMA fibers has been demonstrated [2,3]. Birefringence-assisted FWM in polarization-maintaining (PM) photonic crystal fibers (PCFs) has also been investigated [4][5][6]. Phase matching in such fibers relies on the different phase velocities of the waves propagating in the two polarization modes of the fiber.…”
