Comments

The part below has been removed from the main "Photonic page" I think it is not proper to mix content with creators' and editors' names.

Researchers in photonics

The "other" photonics

In science land we define photonics by the band structure of light that is created basically by very tiny regular arrays of holes on the size scale of the wavelength of the incident light. In fact opalescence is a well known photonic phenomenon that (in nature) is the result of tiny regular arrays of spheres that cause different wavelengths of light at different angles and polarizations to refract non uniformly... At any rate the result is the photon analog of an electronic band structure which is where the term "photonic" comes from. I think this entry needs to include this definition of photonics as, from my point of view, it is far more common than the definition provided. I am definitely not the person to write such an entry though as I know very little about photonics. Fearofcarpet 17:48, 18 Mar 2005 (UTC)

I think you are confusing the noun "photonics" with the adjective "photonic", as in "photonic crystals" and "photonic bandgap". Most applications of photonic phenomena fall into the field of photonics, but the field is broader than that. Photonic crystals already have their own page, and it is linked to from this page.--Srleffler 06:39, 18 November 2005 (UTC)[reply]

University programs in photonics

Please note that this is a photonics’ page. Please provide links to photonics program descriptions, curricula etc. Links to university home pages or laboratory staff listing are not relevant here. --Sergiusz 20:44, 24 August 2005 (UTC)[reply]

I have removed the list of university programs in photonics, per the policy that Wikipedia is not an indiscriminate collection of information. If Photonics were a rare discipline, it would be relevant to list the few schools that have programs in it. It is clear from the size of the list, though, that this is not the case. Articles on subjects should not generally contain a list of universities where that subject is taught. Such a directory is best hosted elsewhere.--Srleffler 00:52, 18 April 2006 (UTC)[reply]

Photonic Clocking

I was just reading about photonic clocking on Slashdot RSS　EMail; it seems like its important.--McDogm 09:53, 19 September 2005 (UTC)[reply]

Updates to main page

I have rewritten the introduction, primarily, taking into account what was already provided by earlier writers and editors. IMHO a key issue for "Photonics" is the overlapping use of synonymous terms. Another challenge arises because "Photonics" is virtually without bounds and is evolving as we speak.

I agree that the condition of the page was not ripe for a listing of key photonics researchers. I have linked the inventors of the first room temperature diode laser which I believe is timely given relevance to "Photonics" at the introductory level.

Perhaps someone else can add more to this page by the time I visit it next.

Jabeles, the lead is way too long now. It includes a lot of pieces that should be moved into the history section, and maybe could use another section on something like "subfields and related fields". And while you're at it, it would sure be useful to have references to go with all that stuff. Dicklyon 01:36, 27 May 2007 (UTC)[reply]

Dicklyon, thanks for pointing out that deficiency. I've put in a bit of work rearranging the material into a new second section. Please feel free to contribute as you see fit. Same goes for others. I think the history of photonics needs, at this point to include some of the important work in 1960s such as that of Yariv (one example) and many others. We should work our way from the 1960s forward in time, not the 2000's backward (that may have been the intent originally).

Too comms focused

The section on photonic research is very narrow, only covers optical communication topics - I'm sure there are many more. Does anyone have time to update? --Opticalgirl (talk) 12:27, 31 October 2010 (UTC)[reply]

Relationship Between Optics and Photonics

The Optics article says "Optics is the branch of physics which involves the behavior and properties of light, including its interactions with matter and the construction of instruments that use or detect it.[1] Optics usually describes the behavior of visible, ultraviolet, and infrared light. Because light is an electromagnetic wave, other forms of electromagnetic radiation such as X-rays, microwaves, and radio waves exhibit similar properties".

The Photonics articles says "The science of photonics[1] includes the generation, emission, transmission, modulation, signal processing, switching, amplification, detection and sensing of light. The term photonics thereby emphasizes that photons are neither particles nor waves — they are different in that they have both particle and wave nature. It covers all technical applications of light over the whole spectrum from ultraviolet over the visible to the near-, mid- and far-infrared. Most applications, however, are in the range of the visible and near infrared light".

There seems to be a large overlap. Discuss.109.154.68.246 (talk) 09:08, 4 March 2011 (UTC)[reply]

If we describe electronics as signal processing with electrons, by analogy we could say photonics is signal processing with photons. or maybe "Photonics is the control, manipulation, transfer and storage of information using light." from [ What is Photonics? ] ? - Rod57 (talk) 18:08, 12 April 2013 (UTC)[reply]

The lead is fine as written. Optics and photonics are different topics. What more can I say? Read both articles again, several times, and think about what you're reading. User:Linas (talk) 03:11, 2 December 2013 (UTC)[reply]

contradictory caption

The picture caption talks of "waves of photons". This makes about as much sense as "deserts of water". Someone should rethink and rewrite the caption. WilliamSommerwerck (talk) 22:33, 18 June 2012 (UTC)[reply]
