Re: Re : Will Quantum Computing Enhance Analog Design? Part 3
@DaeJ--good point; possibly a high level of photonic operation might be more radiation resistant which is an issue for space operations.

However, I do not think jitter will be eliminated by Si Photonics.  I think that fundamental limits will mean there is always some level of jitter.

Re: Re : Will Quantum Computing Enhance Analog Design? Part 3
I think that silicon photonics could be used in the high data rate transmitter and receiver of Satellite. I believe that the cost is a little bit expensive now. Once cost is the acceptable point, this technology would be popular in other application. Then I expect that there is no more jitter and cross talking with noise in the PCB Board.

@yalanand--My guess is we are about 10 years away from large scale photonic transistor integration, maybe even longer.

However, in the field of so-called Silicon Photonics there are commercialized devices with varying levels of integration of optical functions on chips.  A near-term goal is to replaced the so-called "light engine" in datacom and telecom equipment which uses fiber optics to send high data rates.  Today, most such equipment uses lasers, one interface which converts electrical to optical is expensive, and uses lots of power.  An example is a Si Photonic company called Luxtera provides a light engine to Molex for an "active optical cable".

Re: optomechanical crystal
@yalanand: Yes, improving the yield and reliability of the MEMS device is complex because of the existing knowledge of the MEMS device models.  

    Having said that, the 2007 ITRS (International Technical Roadmap for Semiconductors) release has already laid the roadmap for NEMS devices which might eventually replace MEMS devices.  The future for semiconductor is fast changing and help integrate more and more analog within a small area.

@Yalanand: "carbon nanotubes have totally different characteristics..."

   Yes the characteristics of carbon nanotubes is different, it is proving to be a great material to redefine battery technology.  The portable devices will have a long lasting power, which might further reduce the size of cellphones (may get rid of charger module), surveillance drones.  Also it is good material for storage or memory devices.

Re: optomechanical crystal
 With new technology like carbon nanotubes, new semiconductor material (compounds of materials) we will see new devices. 

@amrutah, I think nanotubes will completely change the way we implement systems because carbon nanotubes have totally different characteristics. I think VLSI engineers should start studying about nanotubes because this is going to be the next big technology.

Re: optomechanical crystal
with very little MEMS devices hitting the market we don't have a clear assessment of their reliability.

@amrutah, I totally agree with you. We still have limited knowledge on how MEMS devices fail because limited tools and models are available. How to model the reliability of MEMS is a challenge.

Re : Will Quantum Computing Enhance Analog Design? Part 3
@Blaine, thanks for the post. I am curious to know if optical transistors will completely replace traditional transistor and how long quantum computing will take to come market ?

Re: optomechanical crystal
MEMS systems are utilized in many applications and many industry sectors: consumer (gyroscopes for smartphone, tablets...),  vibrational sensors (safety, ), automotive (motor control) etc...

Due to this wide diffusion the reliability of these devices will be tested very soon and I believe that the result will be good.

@eafpres:

   I agree, with very little MEMS devices hitting the market we don't have a clear assessment of their reliability.  These being mechanical structures are prone vibration and have higher failure rates.

Google "proved" the D-Wave 2 they operate jointly with NASA (mainly paid for by Google) can operate "up to ∼ 108 times faster".
I've written before about the impact the Internet of Things (IoT) will have on electronics sales including the special role played by analog devices in IoT.
Until about a decade ago, thermal energy was considered almost entirely as an analog, bulk phenomena.
Unless you live in a cave without any media access (which, I suppose, would preclude your reading this blog) you have heard about the Internet of Things (IoT).
With large scale integration of analog functions, we can probably bring eyesight to the blind.
