The role of angular slit number and angular slit width on the OAM spectrum
Jayson P. Cabanilla, Nathaniel Hermosa
The uncertainty principle sets the limit for simultaneous measurements of position and momentum, and its angular analogue is realized through angular diffraction. When a beam is sp…
3D Fourier ghost imaging via semi-calibrated photometric stereo
Ritz Ann Aguilar, Nathaniel Hermosa, Maricor Soriano
We achieved three-dimensional (3D) computational ghost imaging with multiple photoresistors serving as single-pixel detectors using semi-calibrated lighting approach. We performed…
Folded transit photometry
Ma. Janelle Manuel, Nathaniel Hermosa
Transit photometry is perhaps the most successful method for detecting exoplanets to date. However, a substantial amount of signal processing is needed since the dip in the signal…
Proper scaling for triangular aperture in OAM measurement
Dina Grace C. Banguilan, Nathaniel Hermosa
A standard triangular aperture for measuring the orbital angular momentum (OAM) of light by diffraction usually has a fixed and limited radius R. This possesses a crucial issue sin…
Probing higher OAM of LG beams via diffraction through translated single slit
Jadze Princeton Narag, Nathaniel Hermosa
Laguerre-Gaussian (LG) beams carry orbital angular momentum (OAM) as a consequence of a singularity in their phase profile. In this work, we probe the OAM of LG beams using a movab…
A paraxial cloak with four lenses of different focal lengths
Miguel Revilla, Joshua Cesar Lorenzo, Nathaniel Hermosa
We demonstrate cloaking with four lenses of different focal lengths. To achieve this, we compute the separation distances between lenses such that the effective ABCD matrix is equa…
Goos-Hänchen shifts due to 2D materials with complex conductivity
Niña Angelica F. Zambale, Jenny Lou B. Sagisi, Nathaniel P. Hermosa
We investigate theoretically the Goos-Hänchen (GH) shift of a p-polarized terahertz beam incident on a 2D material surface with complex conductivity. Taking monolayer graphene to b…
Response of QD to structured beams via convolution integrals
Jadze Narag, Nathaniel Hermosa
We propose a new expression for the response of a quadrant detector using convolution integrals. This expression is easier to evaluate by hand, exploiting the properties of the con…
OAM beams from incomplete computer generated holograms
Niña Angelica F. Zambale, Gerald John H. Doblado, Nathaniel Hermosa
We show that optical beams with orbital angular momentum (OAM) can be generated even with incomplete computer generated holograms (CGH). These holograms are made such that random p…
Subluminal velocity of OAM-carrying beam
Nestor D. Bareza, Nathaniel Hermosa
We report a consequence of the orbital angular momentum (OAM) of a beam to its group velocity. We calculate the group velocity of Laguerre-Gauss beam () with $\ell…
Frequency conversion of structured light
Fabian Steinlechner, Nathaniel Hermosa, Valerio Pruneri +1
We demonstrate the coherent frequency conversion of structured light, optical beams in which the phase varies in each point of the transverse plane, from the near infrared (803nm)…
Propagation dynamics of vortices in Helico-Conical optical beams
Nestor Bareza, Nathaniel Hermosa
We present the dynamics of optical vortices (OVs) that came from the propagation of helico-conical optical beam. This dynamics is investigated numerically by tracking the OVs at se…
Reflection beamshifts of visible light due to graphene

I present calculations of reflection beamshifts, Goos-Hänchen and Imbert-Fedorov shifts, due to the presence of a monolayer graphene on a dielectric media when using a beam with wa…
Direction-sensitive transverse velocity measurement by phase-modulated structured light beams
Carmelo Rosales-Guzmán, Nathaniel Hermosa, Aniceto Belmonte +1
The use of structured light beams to detect the velocity of targets moving perpendicularly to the beam's propagation axis opens new avenues for remote sensing of moving objects. Ho…

Weak amplification is a signal enhancement technique which is used to measure tiny changes that otherwise cannot be determined because of technical limitations. It is based on the…
Weak measurements with orbital angular momentum pointer states
G. Puentes, N. Hermosa, J. P. Torres
Weak measurements are a unique tool for accessing information about weakly interacting quantum systems with minimal back action. Joint weak measurements of single-particle operator…
How orbital angular momentum affects beam shifts in optical reflection
M. Merano, N. Hermosa, A. Aiello +1
It is well known that reflection of a Gaussian light beam () by a planar dielectric interface leads to four beam shifts when compared to the geometrical-optics pre…
