Sensitive analog systems in mixed-signal VLSI circuits may be vulnerable to digital noise. We demonstrate a possible solution by optically remoting charge packets with a multiplequantum-well self-electrooptic effect device in a novel self-linearized mode. c © 2000 Optical Society of America OCIS codes: (230.4110) Modulators; (200.4650) Optical interconnects In such mixed-signal VLSI electronic ...

We present a comprehensive investigation into the complexity of a new private key storage apparatus: a novel silicon photonic physical unclonable function (PUF) based on ultrafast nonlinear optical interactions in a chaotic silicon microcavity that is both unclonable and impossible to emulate. This device provides remarkable improvements to total information content (raw cryptographic material)...

We recently described a general solution to the phase-matching problem that arises when one wishes to perform an arbitrary number of nonlinear optical processes in a single medium [Phys. Rev. Lett. 95, 133901 (2005)]. Here we outline in detail the implementation of the solution for a one-dimensional photonic quasicrystal, which acts as a simultaneous frequency doubler for three independent opti...

Novel fabrication, detection and analysis approaches were employed to experimentally demonstrate scattering reduction by a plasmonic nanostructure operating at 1550 nm. The nanostructure consisted of a silicon nanorod surrounded by a plasmonic metamaterial cover comprised of eight gold nanowires and was fabricated by a combination of electron beam lithography, focused ion beam milling and dry a...

In this paper we present the design of an optical device based on a Herriott multi-pass cell fabricated on a small sized acrylic slab for heat flux measurements using the deflection of a laser beam propagating inside the cell. The beam deflection is produced by the heat flux conducted to the acrylic slab due to a gradient in the refractive index. The use of a long path cell as the sensitive ele...

Today, electron leakage in InP-based separate confinement laser diode has a serious effect on device performance. Control of electron leakage current is the aim of many studies in semiconductor laser industry. In this study, for the first time, a new asymmetric waveguide structure with n-interlayer for a 1.325 μm InP-based laser diode with InGaAsP multi-quantum well is proposed and theoreticall...

In this paper, we propose and analyze a novel compact electrooptic modulator on a silicon-on-insulator (SOI) rib waveguide. The device confines both optical field and charge carriers in a micron-size region. The optical field is confined by using a planar Fabry–Pérot microcavity with deep Si/SiO2 Bragg reflectors. Carriers are laterally confined in the cavity region by employing deep-etched tre...

In this chapter, we describe optical-beam-induced-current (OBIC) and scanning photoluminescence (PL) imaging of extremely large planar LECs that have been frozen to preserve the doping profile. This complements the basics described in Chap. 1 with respect to device mechanism and characterization. We succeeded in resolving the depletion width, for the first time, of a frozen LEC pn junction and ...

We analyze how complicated a linear optical component has to be if it is to perform one of a range of functions. Specifically, we devise an approach to evaluating the number of real parameters that must be specified in the device design or fabrication, based on the singular value decomposition of the linear operator that describes the device. This approach can be used for essentially any linear...
