Mitsubishis Semiconductor division introduced the ML9xx40 Series of distributed feedback laser diodes (DFB-LD), which enables 2.5Gbps-100km transmission in a 0-85C temperature range. Samples are to be available in June 2003 with mass production scheduled to begin August 2003.
Mitsubishis Semiconductor division introduced the ML9xx40 Series of
distributed feedback laser diodes (DFB-LD), which enables 2.5Gbps-100km
transmission in a 0-85C temperature range. Samples are to be available in
June 2003 with mass production scheduled to begin August 2003.
Eliminating the need for temperature control is expected to lower costs,
create smaller devices and lower power consumption. The ML9xx40 Series
provides stable, single wavelength operation under 2.5Gbps modulation over a
wide temperature range because a quarter-wavelength phase-shifted grating is
used. A transmission of up to 100km is possible at the 1550nm laser
operation wavelength, where the optical power absorption in the optical
fibre is minimised.


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.
