Optimization and fabrication of 780 nm DFB lasers for quantum systems

Presented in: SPIE Quantum West 2023 Authors: Riina Ulkuniemi, Luukas Kuusela, Timo Aho, Petteri Uusimaa    Presented in: SPIE Quantum West 2023 Authors: Riina Ulkuniemi, Luukas Kuusela, Timo Aho, Petteri Uusimaa   Laser diode solutions for quantum systems have highly variable requirements, depending on the technology and purpose of the laser used in the application – for instance, quantum control of particles or molecules and excitation of the quantum systems. Requirements of the laser systems used in the mentioned applications are highly demanding, such as single-mode operation, frequency stability over operation lifetime and narrow spectral linewidth. Narrow spectral linewidth can be achieved with Continue reading →

Thermal management optimization in high-power 3D sensing VCSELs

Published in: SPIE LASE 2022 Authors: A. Filipchuk, K. Nechay, R. Ulkuniemi, S. Talmila, P. Uusimaa  Published in: SPIE LASE 2022 Authors: A. Filipchuk, K. Nechay, R. Ulkuniemi, S. Talmila, P. Uusimaa Vertical-cavity surface-emitting lasers (VCSELs) have recently paved their way into the 3D sensing market, specifically in mobile device applications. Vertical emission of VCSELs enables arranging single emitters into high-power 2D arrays. Thus, VCSEL arrays require efficient heat management which can be implemented by the means of packaging, both to improve thermal conductivity and to keep VCSEL chips intact. This becomes particularly important when considering also very high-density laser arrays and 2D matrices for quantum Continue reading →

High-density single-mode laser arrays for quantum systems

Published in: SPIE OPTO 2022 Authors: Riina Ulkuniemi, Petri Melanen, Jari Nikkinen, Jari Ovaskainen, Petteri Uusimaa  Published in: SPIE OPTO 2022 Authors: Riina Ulkuniemi, Petri Melanen, Jari Nikkinen, Jari Ovaskainen, Petteri Uusimaa Quantum systems have highly variable requirements and tailored solutions depending on the technology. For instance, lasers are used for quantum control of particles or molecules and excitation for quantum systems. For the latter purpose, suitable applications are frequency comb generation, timing sources for picosecond pulses, and single photon emitters. Key performance parameters for lasers used in this area are single-mode operation, narrow linewidth, and frequency stability. Wavelength of the lasers Continue reading →
