... of two coherent beams can eliminate the plasmonic Joule losses of light energy in
the metamaterial with thickness less than one tenth of the wavelength of light or,
in contrast, can lead to almost total absorbtion of light. The phenomenon provides
functionality that can be implemented freely across ...
... optical characterization technique, but SPR uses a noble metal
coating on sensors (typically gold) to create a highly sensitive
evanescent field at the metal surface, thus creating conditions
which are extremely sensitive to small changes in the close vicinity
of the surface (∼300 nm). Working with ...
... we will emphasize it in this book since it is a well-established and increasingly important
technology. The beginnings of optical communications can be traced to the inventor of
the telephone, Alexander Graham Bell. In 1880, Bell invented a device he termed the
photophone, which allowed information ...
... lifetimes in the cavities. Unfortunately, the reflow process of SiO2 has to occur with
a high-power carbon dioxide (CO2 ) laser. This process has two major disadvantages.
Firstly, the CO2 laser produces temperatures above 1000 ◦ C on the silicon chip,
which hinders the additional integration of furt ...
... In this work the rst opto-microuidic Lab-On-a-Chip for both the generation and
detection of droplets, entirely integrated in lithium niobate, is presented. The device is
composed of a microuidic stage consisting in a passive droplet generator, where water in
oil droplets are produced by the cross ...
... This thesis is about the reflectance measurement of high reflectivity DBR stacks
by using Fourier Transform Infrared (FT-IR) spectroscopy. First, the basic theory of
optical multilayer is reviewed and then the principle operation of FT-IR spectroscopy is
studied. Followed by method used to simulate ...
... Light emanating from some source, sun, or a light bulb, vibrates in all
directions at right angles to the direction of propagation and is unpolarized.
In optical mineralogy we need to produce light which vibrates in a single
direction and we need to know the vibration direction of the light ray. The ...
... [Sta09a] was proposed by my PhD directors. The development of the idea,
bringing it closer to applications, become the main objective of my PhD work.
High spatial quality of laser beams are of great importance as they are
vastly used in technologies, communications, micro-circuits, science, etc.
... β +iγ where β and γ are real numbers. For example, the solution to the wave equation when
absorption or amplification takes place contains an exponential with a complex argument.
In this case, the imaginary part of φ introduces exponential decay or growth as is apparent
upon examination of (0.6). An ...
... simple. Increase the index contrast and higher integration is possible,
but there are details that make this difficult. The size of the core necessary for single mode operation is much smaller. This leads to tighter
manufacturing tolerances. Many of these tolerances don’t simply scale
with core size ...
... interface between conductors and transparent materials. Combining the high localization of electronic waves with the propagation properties of optical waves,
plasmons can achieve extremely small mode wavelengths and large local electromagnetic field intensities. Through their unique dispersion, surf ...
... Since the publication of the paper where the first fiber Fabry-Perot
interferometer(FFPI) for sensing applications was demonstrated,
more than thirty years ago, a number of configurations of this optical
fiber interferometer have been proposed and used to detect physical,
chemical and biological var ...
