Hundred megahertz spectral bandwith, passively mode-locked laser (Phase I)

百兆赫光谱带宽、被动锁模激光器(第一期)

基本信息

项目摘要

The current Idea to Innovation proposal aims to build, investigate and improve a fully polarization maintaining laser prototype allowing for passive mode-locking of unchirped long light pulses (>500 ps), compatible with low power demands. Mode-locked lasers, radiating pulsed coherent light, form the foundation for various applications ranging from telecommunications, spectroscopy, metrology, to quantum optics. While many different mode-locking techniques have been demonstrate, none of them managed to generate nanosecond pulses with Fourier-limited bandwidth (in the megahertz spectral bandwidth range), characteristics that are required for, e.g., the efficient excitation of molecules or even multiplexing in telecommunication networks. Indeed, our present invention based on a passive mode-locking scheme actually addresses the intrinsic bandwidth and complexity limitations of active mode-locking techniques while setting the base toward a fully integrated system (i.e. transposed to an on-chip CMOS compatible architecture). Our laser scheme is based on the use of a nonlinear medium (i.e. a micro-ring resonator) within a nonlinear amplifying loop mirror, thus offering a reduction of the amount of power required to achieve mode-locking by a nonlinear phase shift, while acting, at the same time, as an ultra-sharp filter limiting the bandwidth of the pulsed laser to a record low 105MHz at a repetition rate of 9.5 MHz. Furthermore, such a scheme present the possibility of generating directly quantum correlated photon pairs from a pulsed excitation, a crucial characteristic for developments in the field of quantum optics. Our project will then focus on the implementation of commercial production processes to build a laser prototype fully based on low-cost and CMOS-compatible components. Our mode-locking laser scheme has already raised significant interest in companies that manufacture laser systems at telecom wavelengths, as well as resellers of photonic systems for applications in the field of quantum optics. We intend to push forward the development of our invention with the aim to increase the value of our intellectual property and enlarge the number of potential customers interested in our technology.
目前的创新想法计划旨在建立、研究和改进一种完全保持偏振的激光原型,允许无啁啾长光脉冲(>500 ps)的被动锁模,兼容低功率需求。锁模激光器发射脉冲相干光,构成了从电信、光谱学、计量学到量子光学等各种应用的基础。虽然已经展示了许多不同的锁模技术,但没有一种技术能够产生具有傅立叶有限带宽(在兆赫光谱带宽范围内)的纳秒脉冲,这些特性是例如有效激发分子或甚至在电信网络中进行多路复用所必需的。事实上,我们基于无源锁模方案的本发明实际上解决了有源锁模技术的固有带宽和复杂性限制,同时将基础设置为完全集成的系统(即,转置到片上CMOS兼容架构)。我们的激光方案基于使用非线性放大环镜中的非线性介质(即微环谐振器),从而减少了通过非线性相移实现锁模所需的功率量,同时,作为一个超锐利滤波器,将脉冲激光的带宽限制在创纪录的低105 MHz,重复频率为9.5 MHz。此外,这种方案提供了从脉冲激发产生直接量子关联光子对的可能性,这是量子光学领域发展的关键特征。然后,我们的项目将专注于商业生产流程的实施,以完全基于低成本和与CMOS兼容的元件来构建激光器原型。我们的锁模激光方案已经引起了制造电信波长激光系统的公司以及量子光学领域应用的光子系统经销商的浓厚兴趣。我们打算推动我们的发明开发,目的是增加我们的知识产权价值,并扩大对我们的技术感兴趣的潜在客户数量。
