Wavelength Electronics Celebrates 30 Years<\/a>\u00a0<\/em><\/h4>\n

Wavelength Electronics turned 30 in October! Since 1993, Wavelength Electronics has solved electronics problems in photonics systems from our factory in Bozeman, Montana. We started with driving laser diodes and controlling their temperatures. Our first products were OEM modules and components that laser engineers could design into their own systems. The vision was to provide benchtop instrument performance in a small package.<\/p>\n

We\u2019ve maintained our focus on LD safety and evolved to offering only high-performance solutions \u2013 very stable current, very low noise, very stable wavelength through temperature stabilities limited only by sensor precision.<\/p>\n

We\u2019re committed to researching new technologies as they emerge, and constantly expanding our capabilities. At present, our CW laser diode drivers<\/a> can modulate in the MHz range. We can scale the output currents to support VCSELs at the low end and pump diodes at the high end. Our temperature controllers<\/a> easily achieve mK stability \u2013 regardless of environmental conditions. We offer both linear and higher efficiency PWM output stages.<\/p>\n

We have chosen to focus on high performance. Our customers leverage our expertise to gain a competitive advantage and develop solutions that significantly improve lives.<\/p>\n

We believe a design is only finished when it can be manufactured repeatedly with high yield. In addition to our knowledge of circuitry, we researched best-in-class electronics manufacturing practices. We\u2019ve invested in automated production equipment \u2013 two SMT lines, a selective solder, AOI. We\u2019ve developed procedures and protocols in our Quality System to consistently achieve a return rate of less than 0.1%. From our humble beginnings with plate-through resistors, we\u2019ve embraced building with the smallest of SMT components \u2013 0201s, BGAs. We also offer our assembly services to local companies. Our team members pride themselves on finding improvements, integrating new technologies, and contributing to our clients\u2019 success.<\/p>\n

Where are we going? Eventually we will be able to drive any semiconductor laser made in all operating modes.<\/p>\n

For now, we are introducing Custom Engineering Services. Custom circuit designs that perfectly fit the system need \u2013 multiple channels, compact size, any combination of form fit and function.<\/p>\n

CASE STUDY: Dual-Comb and Fourier Transform for Fast and High Spectral Spectroscopy<\/a><\/em><\/h4>\n[\/vc_column_text][vc_column_text css=”.vc_custom_1701181619942{margin-bottom: 0px !important;}”]\n

Complex chemical and biological reactions require fast (sub-second) spectroscopy with high spectral resolution. Researchers from Switzerland have developed a Fourier Transform (FT) spectrometer designed around a custom, continuous rotation scanning mirror, enabling millisecond acquisition times while maintaining high spectral resolution in the sub-GHz range. The demonstrated system incorporates the advantages of both FT spectroscopy as well as dual-comb spectroscopy. This design not only uses a single frequency comb for dual-comb spectroscopy, but can prove useful in a variety of spectroscopy applications where high speed, large optical bandwidth, and high spectral resolution are desired.<\/p>\n

Combining FT spectroscopy with dual-comb spectroscopy for fast acquisition and high-spectral resolution requires high precision and stable control of the quantum cascade laser. Wavelength Electronics’ QCL1000 OEM<\/a> driver enabled precise current control with minimal electronic noise. The driver also allows analog wavelength modulation of up to 2-3 MHz. This enabled laser tuning by changing the drive current to the QCL with a triangular current modulation ramp. As laser linewidth is a major concern for QCLs, the QCL1000 OEM minimizes noise to as low as 0.7 \u03bcA up to 100kHz as well as keeping the average current noise density to as low as 2 nA \/ \u221aHz.<\/p>\n

Our QCL driver enables sub-second spectroscopy with high spectral resolution with low noise and stable laser output. This makes the developed rotational FT spectrometer system a reliable tool for dual-comb spectroscopy for applications in reaction and leakage monitoring and in-line process analytical technology.<\/p>\n

CASE STUDY: VCSEL Absorption Spectroscopy of Chip-scale Rubidium Atomic Vapor<\/a>\u00a0<\/em><\/h4>\n

Researchers from the Indian Space Research Organization in Bengaluru, India have developed and demonstrated the absorption spectroscopic capabilities of a chip-scale Rubidium (Rb) atomic vapor cell using a thermoelectric cooler integrated VCSEL light source in a magneto-optic package. The custom 3D-printed design provides real time analysis of spectral data. With over 600 hours of data, absorption resonance lines were recorded and analyzed for transitions 85Rb and 87Rb with absorption amplitude and FWHM data agreeing with known literature values.<\/p>\n

For the compactness and wavelength stability of the design, both the size and stability of the temperature controller are critical in the success of the absorption spectroscopy study. The VCSEL diode required high temperature stability due to the center frequency shifting with change in temperature. To meet these requirements, researchers used Wavelength Electronics’ WTC3243 Temperature Controller<\/a>.<\/p>\n

This magneto-optic Rb atomic cell package proves potential for atomic sensors, particularly in space borne applications or payloads.<\/p>\n
