Power dissipation has become one of the major concerns of VLSI circuit design with the rapid launching of battery operated applications. In high performance designs, the leakage component of power consumption is comparable to the switching component. This percentage will increase with technology scaling unless effective techniques are introduced to bring leakage under control. In this paper, a ...

We propose an optical isolator based on the electro-optic (EO) effect of periodically poled lithium niobate (PPLN). When the EO effect occurs in PPLN under a TE field, each domain serves as a half-wave plate under the quasi-phase-matching condition, and PPLN shows optical activity similar to quartz. The introduction of an additional half-domain to the normal PPLN changes the incident azimuth an...

TABLE 1. Experimental and theoretical results for noise reduction in photon-number or intensity-1/f noise of spectrally filtered solitons. The pulse widths are FWHM values, C is the chirp parameter as defined in G.P. Agrawal: ”Nonlinear Fiber Optics” (Academic Press 1995). The photon-number noise reduction values in parentheses are: * extrapolated for 100 % detection efficiency (experiment) ** ...

A full-bandwidth k-domain linearization method for spectral-domain optical coherence tomography (SD-OCT) is demonstrated. The method uses information of the wavenumber-pixel-position provided by a translating-slit-based wavelength filter. For calibration purposes, the filter is placed either after a broadband source or at the end of the sample path, and the filtered spectrum with a narrowed lin...
