DenseLight Expands Laser Range

Next generation narrow linewidth lasers target high precision remote sensing applications

DenseLight Semiconductors, a subsidiary of  the opto-electronics process company POET Technologies, has unveiled its next generation Constellation Series of Narrow Linewidth Laser (NLWL) solutions.

The new Constellation Series integrated light modules [CBF Series] offers narrow spectral linewidths (e.g., 10, 5 and 1 Khz), excellent Side-Mode Suppression Ratio (SMSR), power stability and a high wavelength stable laser output, according to the company.  

These feature sets are suited for a wide range of high precision remote sensing applications including wind-farm LIDAR; meteorological atmospheric LIDAR; Distributed Acoustic Sensing (DAS); Perimeter Intrusion Detection Systems (PIDS); distributed strain and temperature sensing using Brillouin Optical Time Domain Reflectometry (BOTDR); precision optical metrology & instrumentation; and high resolution optical gas & chemical sensing.

Senior VP of sales and marketing at DenseLight, Bryan Patmon, commented: "Our newest family of laser products delivers the most reliable laser performance with the lowest noise output. We are greatly simplifying the process for customers to create and implement integrated systems and solutions with advanced capabilities."

DenseLight's first Constellation Series product, the CBF-9, is complete with a proprietary specialty laser module fixed into a newly designed hermetically-sealed Butterfly package, as well as an integrated laser driver and temperature controller.  

Premiering with a C-band laser, the CBF series of products will eventually be extended across a wide wavelength range, inclusive of the O, E, S, C and L bands. The new CBF platform can be customized for multiple use and application options to meet customers' specific requirements.

A New Family of Derivative Gain Chips

DenseLight has also expanded its product portfolio of gain chips, based on proprietary InP active waveguide designs to provide high optical gain over a broad wavelength range and near-circular optical far-field profile.

Gain chips are typically integrated in external cavity laser systems as the laser gain source. The gain chip is delivered as chip or chip-on-submount, with high reflectivity (HR) coating on the back facet and low reflectivity anti-reflecting (AR) coating on the angled front facet.

The DenseLight gain chip family will feature very stable operational characteristics as well as superior tuning capabilities. The gain chip product portfolio will offer ASE optical peak wavelength coverage from 1260nm to 1650nm.

DenseLight's portfolio of optical sensing solutions will be demonstrated at the Photonics West 2017 conference in San Francisco, California from January 31 to February 2, 2017.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
