Advanced semiconductor lasers:Ultra-low operating energy and heterogeneous integration with Si photonics devices

Shinji Matsuo, NTT Photonics Laboratories, Japan

Abstract: The electrical power consumed in data transmission systems is now hampering efforts to further increase the speed and capacity at various scales, ranging from data centers to microprocessors. Optical interconnects employing an ultralow energy directly modulated lasers will play a key role in reducing the power consumption. Since a laser’s operating energy is proportional to the size of its active volume, developing high-performance lasers with a small cavity is important. For this purpose, we have developed membrane DFB and photonic crystal (PhC) lasers, in which active regions are buried with InP layer. Thanks to the reduction of cavity size and the increase in optical confinement factor, we have achieved extremely small operating energy and demonstrated 4.4-fJ/bit operating energy by employing wavelength-scale PhC cavity. Reduction of the cost is also important issue because huge number of transmitters are required for short distance optical links. For this purpose, Si photonics technology is expected to be a potential solution because it can provide large-scale phonic integrated circuits (PICs), which can reduce the assembly cost compared with transmitters constructed by discrete devices. Therefore, heterogeneous integration of III-V compound semiconductors and Si has attracted much attention. For fabricating these devices, we have developed wafer-scale fabrication procedure that employs regrowth of III-V compound semiconductors on directly bonded thin InP template on SiO2/Si substrate. A key to realize high-quality epitaxial layer is total thickness, which must be below the critical thickness, typically 430 nm. Thus, membrane structure is quite suitable for heterogeneous integration. I will talk about our recent progress, focusing on ultralow-powerconsumption directly modulated lasers and their photonic integrated circuit. I will also describe progress in heterogeneous integration of these lasers and Si photonics devices.

Transceiver Architectures for Beyond-5G: Challenges and R&D Opportunities, co-organized with SSC-S
May 14 @ 12:00 – 13:00

Presented by IEEE MTT-S Distinguished Microwave Lecturer (DML) Talks:

Transceiver Architectures for Beyond-5G: Challenges and R&D Opportunities, co-organized with SSC-S

By
Dr. Payam Heydari
University of California, Irvine

Date: Thursday, May 14 , 2020

Time: 12:00 PM – 1 PM

Abstract:

The ongoing super-linear growth of world’s population coupled with the worldwide access to internet and the general public’s tendency to use more bandwidth-intensive applications fuel the urgency to enhance wireless infrastructures so as to meet these demands. Consequently, the wireless R&D is headed towards the inception of “Beyond-5G” (e.g., 6G) technology.  This webinar provides a comprehensive overview of challenges and opportunities in designing beyond-5G transceiver architectures capable of achieving high data rates above and beyond 20 Gbps.

Photonics North 2020
May 26 @ 08:00 – May 28 @ 17:00

On behalf of the conference organizing committee,
we invite you to the virtual Photonics North Conference on May 26-28,
2020.  In the midst of a global crisis,
we look forward to meeting with all of you, our colleagues, as we carry on with
the work of advancing optical science and engineering. Join us for outstanding
plenary talks from inspirational thought leaders. Join us for the very best
work from respected and established researchers. Join us for talks from
emerging researchers, presenting what is surely the opening work of brilliant,
burgeoning careers.

Photonics and optics are finally seeing widespread adoption and significant growth into new markets. Photonic devices are being applied to sensing, communications, and even quantum computing. High speed fiber optics and highly integrated subsystems are essential to the rollout of 5G systems. There has never been a better time for research, development, and training in photonics and Photonics North is essential for developing and promoting the ecosystem.

Abstract

5G connectivity is the next technological revolution. This pervasive, ultrafast compute network will connect billions of devices with data on-demand. It will drive economic expansion in many sectors, spawn new products and services, and transform our lives as we know it. Yet, before 5G can deliver on its promises and quality of service (QoS) metrics, wireless systems designers and engineers must overcome sizable challenges.  

Ansys 5G simulation solutions empower these individuals to solve the complexities impeding device, network and data center design. Ansys 5G simulation solutions provide electromagnetics, semiconductor, electronics cooling and mechanical analysis tools to accurately simulate 5G radio and related technologies. The multi-solution platform leverages high-performance computing that can be deployed across the enterprise, allowing designers and engineering experts to collaborate more effectively. 

This seminar will highlight the following 5G engineering challenges: 

·  End User Equipment
