We present a three-dimensional (3-D) analysis of scattering losses due to sidewall roughness in rectangular dielectric waveguides valid for any refractive-index contrast and field polarization. The analysis is based on the volume current method and u

Low-loss air trench structures that permit reduced-size bends in low (/spl Delta/ = 0.7-7%) and medium (/spl Delta/ = 7-20%) index contrast waveguides are demonstrated. Local high index contrast at bends is achieved by introducing air trenches with "

The names of previous after-dinner speakers at this conference read like a Who is Who of Quantum Optics and Photonics research. When the organizers of this conference asked me to present an after-dinner talk I felt honored by the invitation, but also

The zero-point fluctuations in an L–C circuit of finite Q are revisited. The zero-point energy is shown to approach the value of only in the limit of an infinite Q. A Fabry–Perot resonator, on the other hand, has bounded zero-point energies of it

This is the edited text of the Keynote Speech that Professor Haus had been invited to give at the Conference on Fluctuations and Noise in Photonics and Quantum Optics, held at Santa Fe, NM, on 1–4 June 2003. He introduces it as partly an overview,

Quantum equations of motion are developed for broadband soliton propagation in optical fibres with an instantaneous Kerr effect. New terms appear in the nonlinear Schrodinger equation. Hyperbolic secant soliton solutions exist. The initial pulse pert

We present the architecture of a broad-band polarization mode dispersion (PMD) compensator in a feedforward PMD compensation scheme. It is comprised of four stages. The net effect of the first two stages is equivalent to a frequency dependent polariz

A quantum theory for the noise of optical pulses in actively mode-locked lasers is presented. In the presence of phase modulation and/or group velocity dispersion, the linear operator that governs the time evolution of the pulse fluctuations inside t

A real-time estimation technique for first- and second-order polarization-mode dispersion (PMD) is presented. It makes use of the spectrum of telecommunication signals. At the output of the transmission fiber, the signal is tapped and filtered. Three

We propose a module that generates variable second-order polarization mode dispersion (PMD) without producing any first-order PMD. It is based on four identical fixed differential group delay segments arranged in a symmetrical manner. Only one contro
