Abstract

We report broadband all-fiber optical phase modulation based on the photo-thermal effect in a gas-filled hollow-core fiber. The phase modulation dynamics are studied by multi-physics simulation. A phase modulator is fabricated using a 5.6-cm-long anti-resonant hollow-core fiber with pure acetylene filling. It has a half-wave optical power of 289 mW at 100 kHz and an average insertion loss 0.6 dB over a broad wavelength range from 1450 to 1650 nm. The rise and fall time constants are 3.5 and 3.7 μs, respectively, 2–3 orders of magnitude better than the previously reported microfiber-based photo-thermal phase modulators. The gas-filled hollow-core waveguide configuration is promising for optical phase modulation from ultraviolet to mid-infrared which is challenging to achieve with solid optical fibers.

基于光热效应的宽带全光纤空芯充气光纤相位调制器

本文报道了一种基于光热效应的全光纤相位调制方法。通过多物理场仿真研究了相位调制动力学。采用纯乙炔填充的5.6 cm长抗谐振空心芯光纤制作了相位调制器。它在100 kHz时的半波光功率为289 mW，在1450至1650 nm的宽波长范围内的平均插入损耗为0.6 dB。上升和下降时间常数分别为3.5和3.7 μs，比先前报道的基于微光纤的光热相位调制器提高了2-3个数量级。充气空心波导结构有望实现从紫外到中红外的光相位调制，这是固体光纤难以实现的。
