Eblana Unveils 1877nm Single-wavelength Laser Diode

The strained quantum well indium phosphide design is ideally suited for moisture detection
Eblana Photonics has released a single wavelength 1877nm Laser Diode (LD) module for laser spectroscopy applications.

The optically isolated 14-pin butterfly EP1877-DM series laser module is ideally suited for moisture detection in Tuneable Diode Laser Absorption Spectroscopy (TDLAS) applications.

This new laser product expands on Eblana’s existing gas detection product portfolio which already includes lasers for detecting methane (λ = 1654nm), CO2 (λ = 2004nm) and moisture (λ = 1392nm).

The laser is fabricated using Eblana’s discrete mode laser technology platform, which delivers DFB-like performance at a price point geared to high volume applications.

Eblana’s strained quantum well InP design provides stable, high performance, single wavelength operation and a wide degree of current tuning for wavelength control.

The product is ideally suited for H2O detection using the 1877nm absorption line and has a high spectral purity with a typical side-mode suppression ratio of 45dB. The LD has a narrow spectral line width frequency of about 1MHz.

Eblana maintains that the device exhibits exceptional device to device wavelength and performance uniformity. The module is packaged in a standard 14 Pin Butterfly with integrated TEC and optical isolator.

“We are delighted to announce this latest addition to our gas detection product line for TDLAS applications" says Jim Somers, Eblana’s CEO. “We are seeing an increasing trend towards laser-based gas detection systems for high volume deployments. Our customers are successfully displacing older, chemical based gas detection installations with TDLAS on the basis that the laser based system provides higher accuracy, is more reliable and has a lower overall total cost of ownership".

Richard Phelan, director of new product development at Eblana, adds, “Our Discrete Mode laser products are perfectly suited to TDLAS systems where precise wavelength control and stable performance are critical considerations. In response to market demand, we are planning further product releases in this application area in the near future".

Eblana says other centre wavelengths are available on request.

Based in Ireland, Eblana Photonics designs and manufactures laser diodes emitting in the range 680 nm to 2050 nm for communications, sensing and measurement applications.

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.
