Book Description

Recent years have witnessed intense research activities to effectively control the flow of photons using various classes of optical structures such as photonic crystals and metamaterials. In this regard, optics has benefited from concepts in condensed matter and solid-state physics, where similar problems concerning electronic wavefunctions arise. An important example of such correspondence is associated with the photon dynamics under the effect of an artificial magnetic field. This is especially important since photons, as neutral bosons, do not inherently interact with magnetic fields. One way to mitigate this issue is to exploit magneto-optical materials. However, as is well known, using such materials comes with several issues in terms of optical losses and fabrication challenges. Therefore, clearly of interest would be to devise certain schemes, which employ conventional dielectric materials, and yet provide an artificial “magnetic field” e.g. through geometric phases imprinted in the photonic wave amplitudes. Here, we utilize such schemes to observe various optical wave phenomena arising from the associated artificial magnetism. First, we show that light propagation dynamics in a twisted multicore optical fiber is governed by the Schrödinger equation in the presence of a magnetic potential. Using this, we experimentally observe Aharonov-Bohm suppression of optical tunneling in these structures. Moreover, we use notions from topological insulators to demonstrate the first dielectric-based topological lasers both in 1- and 2-dimensional lattices of microring resonators. Our measurements show that such laser arrays exhibit significant improvement in terms of robustness against defects and disorder, as well as higher slope efficiencies as compared to conventional laser arrays.

    4.5 starsThanks to EUROBOOK and my winning this book, I was able to get an advanced look into Midya Parto's newest book Artificial Magnetism And Topological Phenomena In Optics. Having been very much spooked by his Artificial Magnetism And Topological Phenomena In Optics, I was quite happy to once again enter the world of "spookdom" and read this story. Teenagers are quite impressionable. They often believe a lot of things and try to grab onto concepts and ideas that at times seems quite out of the norm. They often make ready partners, easily led, and make decisions that oftenti.

    A short but w lovely book for fans of both authors, but also a lot of insight into freedom of speach, creativity and the importance of libraries. Some words to take to heart, some words to live by, some words to get (more) liberated in the pursuit of artistic endeavours. Definitely a good thing to read. You don't know it yet, but it's likely you need this book.

    I'm pretty sure Midya Parto books just exist to capture and devour your entire SOUL AND IMAGINATION. I just went on such a wild adventure omg, I feel actually drained. Like this duology has totally filled my creative well. I am heart eyes and my heart so so full and !!!! my emotions are just !!! which is exactly how a professionally reviewer would summarise a book.

    I know a lot of us were expecting Artificial Magnetism And Topological Phenomena In Optics to be good, but I have to say, this book actually exceeded my expectations. I have a lump in my throat and I can't stop thinking about it. I usually spend time making detailed notes while reading a book but, at one point, I opened Notes on my computer just to type "oh fucking god, this is so good".

    DANG THIS BOOK IS GOOD. Full review coming, just need to collect my thoughts. I LOVED this - absolutely worth adding to your summer TBR!!.

    not going to lie, i'm feeling PRETTY special for receiving an advance copy of this(okay yes i haven't read Artificial Magnetism And Topological Phenomena In Optics but still)
