Dr. Sidi Aboujja Presents Technical Talks on Latest SOA and Triple Junction Products

Dr. Sidi Aboujja from SemiNex presented two technical talks on our latest SOA array and highly reliable Triple Junction for automotive LiDARs at SPIE Photonics West 2023 last week. These talks capture the technological advancements and application insights so that LiDAR can achieve long range with low cost and small form factors. The abstracts of these talks are listed below.

Technical Paper: High performance semiconductor optical amplifier and array for FMCW LiDAR in high-speed autonomous vehicles


We present an industry-leading semiconductor optical amplifier (SOA) platform that exhibits top performance at both 1550nm and 1310nm used in FMCW (frequency-modulated continuous-wave) LiDAR (Light Detection and Ranging) for autonomous vehicles. The SOA structure is based on a proprietary AlInGaAs material system with multiple quantum wells on InP substrate. The SOAs with curved and tilted straight waveguides were developed and tested. The saturated output power of such SOA at 1550nm and 1310nm can reach higher than 450mW and 600mW. An array of four SOA waveguides at 127um or 500um pitch can deliver total output power over 2 Watts. SOA arrays can also be processed as individually addressable with electrical and optical isolations. Such high performance offers the design freedom to LiDAR systems with various scanning strategies such that long range detection can be realized. The low anti-reflection (AR) coating can achieve 0.01% reflectivity, and the noise figure and near-field mode fields of various SOA configurations are presented and compared. Gain chip based on the curved waveguide for various laser configurations is tested and discussed. The SOA chips and arrays can be integrated into a Silicon Photonic Integrated Circuit (Si PIC) to minimize the total footprint of a LiDAR system and overall cost. They include self-alignment features for the ease of integration and high coupling efficiency on Si PIC.

Technical Paper: High reliability of 1550nm triple junction laser diode for long-range automotive LiDAR


We have developed the world-leading Triple Junction laser diode based on AlInGaAs/InP material systems for LiDAR applications. The monolithic laser structure with tunnel junction layers is designed to reduce the stress and improve the heat dissipation. It has 3x the output power and 2x the wall plug efficiency of a single junction laser due to its low operating voltage and high slope efficiency at 1W/A. A single Triple Junction laser diode at eye-safe 1550nm allows a LiDAR to achieve over 200m detection range in all-weather conditions. It can drastically improve and simplify the LiDAR design compared to other laser choices such as 905nm or fiber lasers. For mass adoption by the automotive industry here we demonstrate the high reliability required for Triple Junction high power laser diodes at 1550nm. The life test was performed on 95um aperture Triple Junction with 2.5mm cavity length in a TO9 package. They were driven at an average power of 700mW with the pulse width of 100 micro-seconds and 10% duty cycle at 90°C. Such stressed electrical and temperature condition is almost 20 times higher than standard operation for automotive LiDAR. We have accumulated for more than 1000 hours of life test on 30 devices. Based on Chi squared distribution analysis and Arrhenius equation the estimated MTTF (mean time to failure) is 248k hours at 20°C and 57k hours at 50°C operating temperature, which is respectively 31x and 7x more than the required 8k hours in automotive applications. We also tested Triple Junction laser diodes up to 100°C without performance degradation and without COD (catastrophic optical damage).

SemiNex Fuels Expansion with New Hires


SemiNex Corporation announces new hires in Engineering and Marketing to support their growth in the long wavelength laser diode market. The appointments of Kenil Bhadani as Production Engineer and Stephanie Arnett as Commercial Specialist come in the advent of product innovations and expansion plans expected to launch in 2019.

A graduate of Worcester Polytechnic Institute and a Six Sigma Green Belt, Kenil Bhadani brings key experience in lean methodologies and statistical controls with his role as Production Engineer. He will manage and maintain the SemiNex production operations and drive improvements in efficiency, costs, quality, capacity and lead-times.

As Mechanical Design Engineer for Walker Magnetic, Kenil implemented a design program that specified products, Bill of Materials, overall configure price quote (CPQ) and worked according to ASME BTH-1-2014 standards to calculate tolerances of various magnets. While at Equifit in 2016, his research on the properties of Neoprene alternatives led to the successful redesign of their sports medicine boot and helped to eliminate allergic reactions.

“Kenil’s commitment to Total Quality Management principles is evident in his past work. He is well-equipped to dramatically improve our production capabilities so that customers experience better quality, performance and service,” said David Bean, SemiNex President.

Stephanie Arnett, who joins SemiNex with over 10 years of experience developing visual content and marketing strategies for brands, is responsible for raising the profile of SemiNex laser diodes as Commercial Specialist in charge of advertising and marketing efforts. Additionally, she works closely with the commercial sales team to ensure the best end to end experience for SemiNex customers.

Before working at SemiNex, Stephanie contracted with creative firms and tech companies in the Boston area on projects ranging from email marketing to virtual reality. As an early adopter of immersive photographic technology, she has produced over a hundred virtual tours and VR campaigns, including a 360º preview for a restaurant launch which generated over 100,000 views on social media.

“SemiNex is poised for a really exciting 2019. There’s a growing demand for eye-safe high power solutions as fully realized automotive LiDAR and machine vision systems are expected to be in the hands of consumers in the next few years,” Stephanie commented. “I’m thrilled to be a part of what is shaping up to be a game-changing technology.”
