Lightwave Logic (LWLG) is a public material and device development company that is commercializing its leading Organic Nonlinear Polymers for a variety of electro-optic devices that will be part of our polymer PIC platform. The primary applications for our polymer PIC platform will in high-speed fiber-optic telecom and data communications. Our development roadmap focuses on addressing 100Gbps opportunities using 25Gbps polymer modulators, and 400Gbps opportunities using 50Gbps modulators. We will be advancing our modulator performance to data rates beyond 50Gbps.  Our materials and devices are extendable into other applications, including sensing, IoT, defense, and consumer markets. We are seeking a Laser diode design engineer to work in our facility in Englewood, CO (as part of the Denver Tech Center). Lightwave offers competitive compensation and benefits along with a fast-paced working environment.

Lightwave Logic is seeking an experienced Laser Diode design engineer with design, fabrication, test and characterization experience in 1310nm and/or 1550nm InP designs to enhance the company’s activities in developing our polymer PIC platform. This position requires hands-on experience in the design of high speed InP laser diodes for fiber optics working with fabrication plants, and epitaxial foundries.   Design for manufacturing, wafer testing, characterization as well as working with III-V foundries on PDKs for qualification would be a plus.   The successful candidate will play a key role in the development of integrated lasers for Lightwave Logic’s proprietary polymer PIC platforms.

Specific duties will include:
• Design of laser diode structures/devices with InP at 1310 and 1550nm wavelengths for high speed fiber optic applications.   Design experience with InP DFB lasers with typical regrowths is required.  Design experience with DBRs, tunable lasers would be a plus.
• Familiarity of III-V compound semiconductors and silicon based material systems.
• Ability to create and design new laser diode structures in III-V materials that will integrate with EO polymers using standard (and/or customized) modeling and simulation packages that are commercially available.
• Experience with production fabrication foundry processes such as epitaxial stacks and process flows is required (as a support for the laser design models and simulations).
• Basic optical high speed characterization and test skills experience needed
• Working effectively as part of an inter-disciplinary engineering team that includes device designers, micro-fabrication engineers, packaging, chemists, and test engineers and technicians.
Experience and Education Requirements
• Minimum B.S. or M.S. (preferably PhD) in a relevant field, preferably physics, or electrical or optical engineering.
• Post graduate experience in laser diode design for high-speed photonic devices as part of a PIC platform. A plus would be a solid background in III-V and/or silicon photonic PIC platforms and experience designing laser emitters for commercial PIC circuits.
• Three to five years’ experience working in III-V laser diode emitter design.  A plus would be experience in a commercial advanced development and manufacturing environment where III-V PIC platforms have been productized.
