摘要： A reflective optical switch for use in optical systems, such as fiber optic communications networks, is disclosed. The optical switch includes not only signal transmission characteristics, but also signal reflection capability. The optical switch includes a semiconductor substrate having first and second optical signal waveguides disposed thereon. The two waveguides intersect one another at a selected angle to form an intersection region. A thermal element is disposed atop the intersection region and can be activated to alter the index of refraction of a portion of the intersection region. An optical signal passing through the intersection region is diverted from one waveguide to another according to the heating of the intersection region by the thermal element. A reflective component disposed in a terminal end of one of the waveguides reflects selected optical signals back to the source from which they came.

摘要： An optical fiber for reducing modal dispersion and increasing both travel distance and transmission speed. A core center is formed in the core of the optical fiber. The core center is doped with impurities, is hollow, or is pulled at a lower temperature to increase diffraction of the core center. The core center discriminates the low order modes such that only the high order modes are present in the optical fiber. Because the low order modes are absorbed or otherwise discriminated against, the range of propagation constants is reduced and modal dispersion is likewise reduced. High order modes can be launched in the optical fiber using a lens whose center portion is obscured or by using a diffractive lens to couple a source to the optical fiber.
摘要翻译：一种用于减少模态色散并增加行进距离和传输速度的光纤。核心中心形成在光纤的核心。核心中心掺杂有杂质，是中空的，或者在较低温度下被拉伸以增加核心中心的衍射。核心中心鉴别低阶模式，使光纤中仅存在高阶模式。由于低阶模式被吸收或以其他方式区分，所以传播常数的范围被减小，并且模态色散同样降低。可以使用其中心部分被遮蔽的透镜或通过使用衍射透镜将光源耦合到光纤而在光纤中发射高阶模式。

摘要： A redundant optical signal transmission and reception system is disclosed to enable information exchange via an optical communications network without data loss in the event of optical transmitter or receiver failure. In one embodiment, the redundant optical signal system includes a primary transmission link comprising a plurality of optical transmitters and a multiplexor for modulating and combining electrical signals into a primary multiplexed optical signal. In the event of failure of an optical transmitter, a backup transmission link is activated to compensate for the malfunctioning transmitter. The backup transmission link utilizes a backup optical transmitter to modulate the electric signal formerly received by the malfunctioning optical transmitter. The backup transmission link combines the backup optical signal with the primary multiplexed optical signal to form a complete optical signal for transmission over the optical network. In another embodiment, a similar process is performed for providing backup optical signal reception.

摘要： An optical signal production and modulation system that enables a multiplexed optical signal to be created for transmission without the use of more traditional laser-based optical transceivers. The system includes a light source library and a plurality of modulating optical transceivers. The light source library receives a composite wavelength un-modulated light signal, amplifies it, and separates it into discrete signal channels. Each of these channels is sent to a modulating optical transceiver, which employs a combination of lenses, reflective components, and a pin diode to modulate the channel with the desired data to be carried. The modulated channel can then be forwarded for multiplexing and transmission via a communications network.
