Oclaro Develops Minute Ultra-bright AlInGaP Laser Diode For Displays

The 3.8mm diameter super-bright device delivers more power but uses less energy. This is thanks to new processes, including an optimised waveguide structure and fine-tuning of the laser device structural parameters

Oclaro has developed the HL63153AT, a tiny red laser diode that delivers 150mW single-transverse-mode optical output power at 638nm.

The AlInGaP based laser offers 25 percent more power than its predecessors. Distributor, the Optoelectronics Company says this is currently the highest single-transverse-mode optical output power at a red wavelength available on the market.

Technology breakthrough enables higher power

The massive increase in output power is due to a technology breakthrough which Oclaro accomplished by developing new processes, including an optimised waveguide structure, and fine-tuning the laser device structural parameters.

The consequent leap forward in performance enables a brighter, more vibrant high-lumen image display for compact mobile devices such as pico projectors, smartphones and mobile gaming devices while greatly decreasing power consumption.

“System designers are working on the development of ever more compact RGB modules for the rapidly expanding mobile display market", says Tony Pope, M.D., the Optoelectronics Company. “The Oclaro HL63153AT addresses their need for a light source that combines high brightness and high operating temperature range with a small-form-factor package which is fundamental to further miniaturisation".

Quest for low energy and long battery life

Size reduction of mobile, handheld devices which employ RGB laser technology is often limited by the power requirements of the display which must have vibrant colour and sharp images while still offering low energy consumption and a long battery life. The Oclaro HL63153AT will benefit manufacturers with its low power consumption of only 0.6W in a tiny 3.8mm-diameter TO industry-standard package.

Takayuki Kanno, President, Oclaro Japan, comments, “This newest red laser diode has been designed as a direct result of customer requests for a shorter wavelength diode that delivers higher power in a thin package".

The introduction of the HL63153AT is well-timed as a global company announces what it says is the highest resolution smartphone screen to date which is also the slimmest available on the market with the bonus of reduced power consumption and extended battery life.

Oclaro HL63153AT specifications

The HL63153AT delivers 150mW single transverse mode optical output power from a tiny 3.8mm package at a typical wavelength of 638nm. It has a low operating current of 230mA and threshold current of 75mA. Operating voltage is only 2.7V and LD reverse voltage is 2V. Operating temperature is from -10 to +600C.

As well as laser displays, the Oclaro HL63153AT is ideal as a light source for optical equipment and small laser modules.

Oclaro’s high performance laser diodes are proven to consume a low operating current which extends battery life while maintaining the integrity of the laser diode power in a variety of applications such as range finding, line levelling construction systems and biomedical applications.

The HL63153AT will be in full production from February 2014. Oclaro high performance laser diode samples may be requested through the Optoelectronics Company.

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.
