Universal relations for coupling of optical power between microresonators and dielectric waveguides [PDF]

open access: yes, 2000
The most basic and generic configuration, which consists of a unidirectional coupling between a ring resonator and a waveguide, is considered. The fundamental working equations required to describe the associated power transfer are derived and the ...

Topological Phenomena in Classical Optical Networks [PDF]

open access: yes, 2016
We propose a scheme to realize a topological insulator with optical-passive elements, and analyze the effects of Kerr-nonlinearities in its topological behavior. In the linear regime, our design gives rise to an optical spectrum with topological features

Polarization singularities from unfolding an optical vortex through a birefringent crystal [PDF]

open access: yes, 2004
Optical vortices (nodal lines and phase singularities) are the generic singularities of scalar optics but are unstable in vector optics. We investigate experimentally and theoretically the unfolding of a uniformly polarized optical vortex beam on ...

Simulating quantum-optical phenomena with cold atoms in optical lattices [PDF]

open access: yes, 2010
We propose a scheme involving cold atoms trapped in optical lattices to observe different phenomena traditionally linked to quantum-optical systems. The basic idea consists of connecting the trapped atomic state to a non-trapped state through a Raman ...

Marsilio Ficino's Allegorical Reading of Optical Phenomena

open access: yesTeorie vědy, 2020
As a Platonist, Marsilio Ficino (1433–1499) was deeply interested in light  and its qualities. As a matter of fact, the metaphysics of light is so fundamental for him that it appears, treated more or less systematically, almost in all of his works. As a

Polarization and energy dynamics in ultrafocused optical Kerr propagation [PDF]

open access: yes, 2002
Developing a complete vectorial description of optical nonparaxial propagation of highly focused beams in Kerr media, we disclose a family of new phenomena.

Mutual optical injection in coupled DBR laser pairs [PDF]

open access: yes, 2009
We report an experimental study of nonlinear effects, characteristic of mutual optical coupling, in an ultra-short coupling regime observed in a distributed Bragg reflector laser pair fabricated on the same chip.

Stacking-symmetry governed second harmonic generation in graphene trilayers [PDF]

open access: yes, 2018
Crystal symmetry plays a central role in governing a wide range of fundamental physical phenomena. One example is the nonlinear optical second harmonic generation (SHG), which requires inversion symmetry breaking. Here we report a unique stacking-induced

Cavity optomechanics with arrays of thick dielectric membranes [PDF]

open access: yes, 2016
Optomechanical arrays made of structured flexible dielectrics are a promising system for exploring quantum and many-body optomechanical phenomena.

Optics in Estonia: Research and Innovation Highlights

open access: yesEngineering Proceedings, 2023
Based on citation data, an overview of that part of Estonian basic physical research where optical phenomena or optical methods themselves are the subjects of study is given. The second part of the overview introduces the design and production of optical
