Talk:Optical computing

message: AFAIK While photons are much faster than electrons both electrical current and electromagnetic waves propagate at the speed of light. What matters is the heat dissipated and the transistor switching times. ---- Julian
NB: This page is meant to emphasize the role of photons and photonics in optical computing. Also "photonic computing" is a term coming into more and more use ... perhaps because photon computing needs to be differentiated from quantum computing ... or it sounds more exotic than optical computing.

message: This article appears to contradict itself on the issue of power consumption, first saying it will reduce it then saying that reduced power consumption is a myth. - Whitepaw (talk) 14:07, 23 September 2009 (UTC)

message: Compared to electrons, photons are much faster – light travels about 30 cm, or one foot, in a nanosecond – and have a higher bandwidth.

message: The links at the bottom are mostly "broken". An one of them points to a site where you have to pay $25 to see the content... I think we could do better looking for links! I'm going to check again in a few days (in case the breakage is temporary) and remove the broken links, an hopefully add a few non-broken ones to replace them.

message: The 'Misconceptions, challenges and prospects' first lists a misconception about power usage in short range optical communication. Doesn't that belong in an article about optical communication, not computing? Pixelgel (talk) 04:22, 3 March 2011 (UTC)

thread_title:  stray text 

message: The term "optical computing" has been used for decades to refer to any kind of (numeric or mathematical) computation done using light, such as the canonical 4F processor.  But this article currently only reflects the much narrower area of digital optical computing.  An expansion of the article would be great.  Some starter sources might be Saleh and Teich, "Fundamentals of Photonics," or Goodman, "Fourier Optics." WakingLili (talk) 01:14, 15 November 2012 (UTC)

:: North­eastern Uni­ver­sity assis­tant pro­fessor of physics Swastik Kar and his col­league Yung Joon Jung, an asso­ciate pro­fessor in the Depart­ment of Mechan­ical and Indus­trial Engi­neering,
:: They dis­cov­ered that light-​​induced elec­trical cur­rents rise much more sharply at the inter­sec­tion of carbon nan­otubes and sil­icon, com­pared to the inter­sec­tion of sil­icon and a metal, as in tra­di­tional pho­to­diode devices. “That sharp rise helps us design devices that can be turned on and off using light,” Kar said.
