A rigorous coupled-wave analysis of birefringent holographic gratings with periodically-modulated dielectric tensor along an in-plane direction and tensor variations in the thickness direction
Masud Mansuripur, Per Kristen Jakobsen
Diffraction of light upon interaction with thick slabs of a dielectric material having a periodic modulation of its refractive index (or dielectric tensor) is typically studied wit…
Simultaneous measurement of refraction and absorption with an integrated near-infrared Mach-Zehnder interferometer
Antonia Torres-Cubillo, Alejandro Sánchez-Postigo, Jana Jágerská +2
Most integrated evanescent-field photonic sensors measure changes in either the real part or the imaginary part of the complex refractive index of the sample, i.e., refraction or a…
Hilbert phase microscopy based on pseudo thermal illumination in Linnik configuration
Mikołaj Rogalski, Maria Cywińska, Azeem Ahmad +4
Quantitative phase microscopy (QPM) is often based on recording an object-reference interference pattern and its further phase demodulation. We propose Pseudo Hilbert Phase Microsc…
Theoretical analysis of Fresnel reflection and transmission in the presence of gain media
Masud Mansuripur, Per K. Jakobsen
When a monochromatic electromagnetic plane-wave arrives at the flat interface between its transparent host (i.e., the incidence medium) and an amplifying (or gainy) second medium,…
Fresnel reflection and transmission in the presence of gain media
Masud Mansuripur, Per K. Jakobsen
When a monochromatic electromagnetic plane-wave arrives at the flat interface between its transparent host (i.e., the incidence medium) and an amplifying (or gainy) second medium,…
Label-free chip-based evanescent light scattering super-resolution and superior-contrast optical microscopy (cELS)
Nikhil Jayakumar, Firehun T Dullo, Vishesh Dubey +7
Chip-based Evanescent Light Scattering (cELS) utilizes the multiple modes of a high-index contrast optical waveguide for near-field illumination of unlabeled samples, thereby repos…
Study of waveguide background at visible wavelengths for on-chip nanoscopy
David A. Coucheron, Øystien I. Helle, James S. Wilkinson +4
On-chip super-resolution optical microscopy is an emerging field relying on waveguide excitation with visible light. Here, we investigate two commonly used high-refractive index wa…
On the Nature of the Sommerfeld-Brillouin Forerunners (or Precursors)
Per K. Jakobsen, Masud Mansuripur
We present a brief overview of Sommerfeld's forerunner signal, which occurs when a monochromatic plane-wave (frequency ω=ω_s) suddenly arrives, at time t=0 and at normal incidence,…
Influence of laser spot size at diffuser plane on the longitudinal spatial coherence function of optical coherence microscopy system
Kashif Usmani, Azeem Ahmad, Rakesh Joshi +3
Coherence properties and wavelength of light sources are indispensable for optical coherence microscopy/tomography as they greatly influence the signal to noise ratio, axial resolu…
Constructing a partially transparent computational boundary for UPPE using leaky modes
David Juhasz, Per Kristen Jakobsen
In this paper we introduce a method for creating a transparent computational boundary for the simulation of unidirectional propagation of optical beams and pulses using leaky modes…
Structured illumination microscopy using a photonic chip
Øystein I. Helle, Firehun T. Dullo, Marcel Lahrberg +2
Structured illumination microscopy (SIM) enables live cell, super-resolution imaging at high speeds. SIM uses sophisticated optical systems to generate pre-determined excitation li…
Study of longitudinal coherence properties of pseudo thermal light source as a function of source size and temporal coherence
Azeem Ahmad, Tanmoy Mahanty, Vishesh Dubey +3
In conventional OCT, broadband light sources are generally utilized to obtain high axial resolution due to their low temporal coherence (TC) length. Purely monochromatic (i.e., hig…
Leaky Modes of Solid Dielectric Spheres
Masud Mansuripur, Miroslav Kolesik, Per Jakobsen
In the absence of external excitation, light trapped within a dielectric medium generally decays by leaking out, and also by getting absorbed within the medium. We analyze the leak…

Masud Mansuripur, Miroslav Kolesik, Per Jakobsen
In the absence of external excitation, light trapped within a dielectric medium generally decays by leaking out (and also by getting absorbed within the medium). We analyze the lea…
