Albis Optoelectronics presents 20 GHz high-power photodetector
At the upcoming OFC in San Diego, Albis will present its new high power, highly linear microwave photodetector, designed for direct optical- to-electrical conversion of RF-modulated optical signals at 20 GHz. The small, rugged and hermetic PQW package makes the detector suitable for installation in systems operated under severe environmental conditions. The photodiode inside this module is a high power, high linearity Albis photodiode chip, designed to operate over a wide
range of wavelengths from 1260 to 1620 nm. This photodiode is also available mounted on an AlN carrier. It offers a typical bandwidth of 22 GHz for photocurrents up to 50 mA, a responsivity of 0.5 A/W and high linearity of +30 dBm OIP3 @ 20 GHz, 30 mA. Typical applications include analogue optical links, microwave photonics and radio-over-fibre. Albis Optoelectronics is a leading designer, developer and manufacturer of high-speed photodiodes. Since more than 15 years, the company has offered the broadest portfolio
of Telcordia qualified InP and GaAs photodiodes for datacom and telecom applications in the industry. All photodiode products are manufactured in-house in Albis’ dedicated clean-room facilities. Product highlights include: PIN photodiodes for 10G, 25G and 40G digital and analogue receivers. Low bias, top illuminated APDs for 2.5G and 10G OLT/ONUs. 25G APDs for 28 Gbaud PAM-4 and 100GBASE-ER4 applications. Side- illuminated monitor diodes and monitor diode arrays. Photodiodes with integrated lenses and optical
filters. And last but not least hermetically packaged, short and long wavelength microwave photodetectors up to 30 GHz. Find out more by visiting our booth 4603!
No data traffic without Axetris microlenses
Axetris has been providing microlenses to the communication industry for more than 15 years. Microlenses are omnipresent in telecom and datacom solutions such as wavelength selective switches (WSS), optical transceivers for data centres and long-haul coherent communications components. It all started with Passive Optical Network (PON) components for the megabit telecommunication era. Today, Axetris contributes cost-attractive microlenses and microlens arrays to the advance of Gigabit internet age, where hyperscale data centres and service providers require more efficient, economical and faster solutions. Customised silicon and fused
silica microlenses and microlens arrays Axetris microlenses are made of high-quality optical materials like silicon and fused silica, which have optimal properties for optical communication solutions and many other applications like IR and UV wavelength ranges. Axetris produces microlenses with customised lens designs, and can also add auxiliary features, such as fiducials and metal or solder pads. Microlens chips are provided in the form of single-lenses or one- and two-dimensional lens arrays, which can support single- and multi- channel coupling schemes. Advantages We supply sub-millimetre chip size, down to a few hundred microns with thicknesses of also down to 100 µm. This dimension enables compact packaging
and miniaturised optical setups. Microlenses are manufactured by well-established micro-machining processes, the same techniques used in the fabrication of silicon photonics: i.e., photo-lithography, thermal reflow, and plasma etching. These micro-machining techniques guarantee sub- nanometre surface roughness,
high-precision pitch accuracy for microlens arrays, and good control of the lens aspherical profile given by customised lens designs. The wafer-level processes allow scalability to high volume production and eventually cost- attractive solutions.
