Solutions and Approaches to Break Opto-electronic Device Limitations

By Ke Liu | Posted: 15 May 2015

Starting from the first talk on general opto-electronic device limit and integration for silicon-based devices, presented by Thomas Koch here at the Nanophotonic Devices Incubator, the potential solutions for both the length minimization and power minimization were addressed. For example, Si photonics with high-index contrast and precision fabrication allow energy per bit to be further reduced using optical resonance enhancement for lower capacitance. Combining both resonant optical transition and resonant electronic transition (i.e. Q dot in a ring or nano-cavity), we may simply compound these effects (provided we remain outside strong coupling regime). However, some issues we still need to consider in the future, for instance, if a single-electron modulator is actually feasible, what are the statistical implications?

Electro-optic modulator (EOM) has been identified as one of the key drivers for optical communications. Because of the weak non-linear electro-optical properties of Silicon, such EOM require large footprints and higher power consumption. A dual cavity modulator device that uses a coupling modulation scheme breaks the energy-bandwidth limit, presented by Juejun Hu. The combination of 0.26 aJ energy per bit and >200 GHz optical 3 dB bandwidth positions the dual cavity EOM well beyond the performance domains attainable in classical intra-cavity EO modulators.

Focus on Google Glass at Applied Industrial Optics

By Arlene Smith, Ph.D. | Posted: 28 May 2014

I love my smartphone.

When I started university, mobile phones were relatively new. I turned 18 and got my first phone – a Nokia with both calling and texting capabilities.  A few years later, I upgraded to a newer model. This one had a built-in FM radio and the keypad had a blue backlight. It was the high-tech wave! But I think we all know how technology has progressed since then.

Perspective views from Industry & Government on Nanophotonics

By Ke Liu | Posted: 16 May 2014

Similar to the success of dense electronic component integration towards creating VLSI circuits, the photonic and optoelectronic industry is following similar integration schemes, terming the name “photonic integrated circuits” (PIC). However, all-Silicon PIC cannot currently complete all the functions. Alternatively, III-V platform, such as InP material system, still occupies a good position in the future. What are the viewpoints of industry and government to guide future research towards faster time-to-market?

Some counterintuitive lessons learned from the OSA BIOMED meeting

By Kyle Quinn | Posted: 6 May 2014

With the conclusion of another BIOMED meeting, I once again left Miami impressed by the many excellent talks, clever imaging solutions, and novel biological insights.  I’ve appreciated the opportunity to share my thoughts about the conference through this blog, and in conclusion, I thought I would highlight three things that I was rather surprised to learn.

What’s New in Applied Optics Research? AIO 2014

By Arlene Smith, Ph.D. | Posted: 5 May 2014

Applied Industrial Optics (AIO), now in its 5th year, focuses on research which utilizes optics and photonics technology to solve real-world problems. This year, speakers and attendees who are engaged in applied research will descend on Seattle in mid-July, to get a taste of what’s new in applied optics research. or the next three months, I will be blogging about the topics and speakers of this year’s meeting.
