This proposal was submitted in response to the solicitation NSF 01-65 on "Ultra-High Capacity Optical Communications and Networking." We have recently introduced a hollow dielectric optical fiber which utilizes a one-dimensional photonic crystal to guide light. This fiber is predicted to have an unrivaled degree of confinement of the electromagnetic energy density in the hollow core - allowing for broad-band and low loss transmission with substantially decreased non-linear behavior. In this proposal we will focus our efforts on creating novel in-fiber optical devices based on the unique characteristics of this hollow waveguide. We will theoretically examine the effects of inducing large periodic modulations along the axial direction of the fiber. These are expected to open large photonic band gaps in the direction of propagation. In particular we will study the possibility of creating high Q cavities within the fiber. Application to high speed all-optical switching and other novel devices will be illustrated. The ability to form all-optical devices in a fiber has many technical advantages, reduction of coupling losses to transmission line - not being the least. It also opens new opportunities to low cost fabrication of optical devices based on fiber production processes. Our efforts will be directed towards the formulation of a general theoretical approach, the design, development and the experimental realization of in-fiber optical devices based on the axially modulated hollow dielectric omnidirectional waveguide.

该提案是为了响应“超高容量光学通信和网络”的招标NSF 01-65。我们最近引入了一个空心的介电光纤，该光纤利用一维光子晶体来引导光。预计该纤维在空心核中具有无与伦比的电磁能密度的限制程度 - 可实现宽带和低损耗的传播，并大大降低了非线性行为。在此提案中，我们将基于此空心波导的独特特征来创建新型的纤维光学设备。从理论上讲，我们将研究沿纤维的轴向诱导大型周期调制的影响。这些预计将在传播方向上打开较大的光子带隙。特别是我们将研究在纤维内部产生高Q腔的可能性。将说明高速全光开关和其他新型设备的应用。在纤维中形成全光设备的能力具有许多技术优势，减少了与传输线的耦合损失 - 并非至少。它还为基于纤维生产过程的光学设备制造低成本制造的新机会。我们的努力将针对一般理论方法的制定，基于轴向调制的空心介电透明度波导的纤维内设备的设计，开发和实验实现。
