Broadband all-fiber mid-infrared supercontinuum generation in an As2S3-polycarbonate hybrid microtaper
We present a coherent supercontinuum (SC) spanning a 1.1–3.9 µ m wavelength range from propagation in a three-stage cascade of nonlinear and dispersive fibers, including a silica fiber, a ZBLAN fiber, and a robust and dispersion-engineered As _2 S _3 microtaper. In the first stage made of silica fib...

| description | We present a coherent supercontinuum (SC) spanning a 1.1–3.9 µ m wavelength range from propagation in a three-stage cascade of nonlinear and dispersive fibers, including a silica fiber, a ZBLAN fiber, and a robust and dispersion-engineered As _2 S _3 microtaper. In the first stage made of silica fiber, a pump pulse undergoes soliton fission, creating a fundamental soliton that subsequently redshifts through soliton self-frequency shift (SSFS) to a center wavelength of 2.14 μ m. In the second stage made of ZBLAN fiber, the fundamental soliton becomes a higher order soliton and experiences a second round of soliton fission creating another fundamental soliton that would shift up to a wavelength of 2.86 µ m via SSFS. In the third stage, the As _2 S _3 microtaper generates a SC that covers the wavelength range of 1.1–3.9 µ m. The As _2 S _3 microwire design with a diameter of 4.4 µ m and a short length of 25 mm provides anomalous dispersion and high mode confinement to the 2.86 µ m soliton while mitigating propagation losses. This all-fiber passive cascade allows a small footprint and alignment-free operation. Numerical simulations match the experimental results and confirm the high coherence of the generated SC. |
