光学相干断层扫描（OCT）是一种广泛应用的三维（3D）光学成像方法，具有许多生物医学和非医学应用。OCT系统的小型化、成本降低和功能增强对于未来新兴的临床应用至关重要。提出了一种具有双偏振、双平衡、同相和正交（IQ）检测的硅光子集成电路扫频OCT（SS-OCT）相干接收机。我们展示了IQ偏振分辨检测的多种功能，包括：复共轭抑制的全范围OCT、偏振分集检测和偏振敏感OCT。据我们所知，这是用于OCT的硅光子集成接收器的首次演示。集成相干接收器为SS-OCT提供了小型化、低成本的解决方案，也是迈向具有良好性能和多功能能力的完全集成高速SS-OCT系统的关键一步。随着性能的进一步提高和成本的降低，光子集成技术有望大大提高OCT系统在现有应用中的渗透率，并实现新的应用。2015美国光学学会Optical Society of America
Optical coherence tomography (OCT) is a widely used three-dimensional (3D) optical imaging method with many biomedical and non-medical applications. Miniaturization, cost reduction, and increased functionality of OCT systems will be critical for future emerging clinical applications. We present a silicon photonic integrated circuit swept-source OCT (SS-OCT) coherent receiver with dual polarization, dual balanced, inphase and quadrature (IQ) detection. We demonstrate multiple functional capabilities of IQ polarization resolved detection including: complex-conjugate suppressed full-range OCT, polarization diversity detection, and polarization-sensitive OCT. To our knowledge, this is the first demonstration of a silicon photonic integrated receiver for OCT. The integrated coherent receiver provides a miniaturized, low-cost solution for SS-OCT, and is also a key step towards a fully integrated high speed SS-OCT system with good performance and multi-functional capabilities. With further performance improvement and cost reduction, photonic integrated technology promises to greatly increase penetration of OCT systems in existing applications and enable new applications.
