Bottom Line: We demonstrate generation of Cerenkov radiation at 850 nm in a higher-order-mode (HOM) fiber.The LP02 mode in this solid, silica-based fiber has anomalous dispersion from 690 nm to 810 nm.The HOM fiber provides a valuable fiber platform for nonlinear wavelength conversion with pulse energies in-between index-guided silica-core photonic crystal fibers and air-core photonic bandgap fibers.

ABSTRACT
We demonstrate generation of Cerenkov radiation at 850 nm in a higher-order-mode (HOM) fiber. The LP02 mode in this solid, silica-based fiber has anomalous dispersion from 690 nm to 810 nm. Cerenkov radiation with 3 nJ pulse energy is generated in this module, exhibiting 60% energy conversion efficiency from the input. The HOM fiber provides a valuable fiber platform for nonlinear wavelength conversion with pulse energies in-between index-guided silica-core photonic crystal fibers and air-core photonic bandgap fibers.

g003: (a) Experimentally measured (solid) and calculated (dashed) Cerenkov pulse energy as a function of input pulse energy. Inset: Experimental results compared with simulated Cerenkov pulse energy at input pulse energies below 0.8 nJ.

Mentions: (a) Measured spectra at various pulse energies showing soliton generation, soliton self-frequency shift, and Cerenkov radiation. (b) Simulated spectra with the same input conditions. All traces are taken at 0.2 nm spectral resolution. The soliton and Cerenkov radiation are marked by arrows. The input wavelength and the zero-dispersion wavelength (ZDW) are denoted by dashed lines and the input pulse energy (E) is indicated on each trace.
