Albis releases new photodiodes for 200G and beyond
At the upcoming OFC Exhibition 2025, Albis Optoelectronics will be showcasing its latest cutting-edge photodiodes, designed to meet the demands of next- generation high speed optical communications. PD50Y1 is a compact 200G photodiode chip sporting an unsurpassed responsivity, targeting next-gen optical transceivers in data centers and telecom applications. This photodiode features an integrated backside lens for easy and efficient optical coupling, and supports up to 200 Gbps per channel, ensuring superior data transmission speeds. The chip topside pads are optimized for flip-chip soldering processes using AuSn or SAC305. Additionally, Albis releases its
new PD80X1 photodiode chip, designed for advanced 400G per lane applications, pushing the boundaries of optical communication capabilities. This chip is ideal for high-density, high-bandwidth applications, making it a perfect fit for future- proof optical networks. With over 20 years of experience, Albis Optoelectronics specializes in designing and manufacturing Telcordia qualified InP and GaAs photodiodes. Their extensive product range includes PIN photodiodes for various digital and analog receivers; high power photodiodes; low bias, high sensitivity APDs for 28 Gbaud PAM-4 and 100GBASE- ER4 applications; monitor photodiodes; photodiodes with integrated lenses; hermetically packaged, short and long-wavelength microwave
photodetectors up to 40 GHz. All products are manufactured in-house at their state-of-the- art clean-room facilities in Rüschlikon, Switzerland. Attendees of OFC Exhibition 2025 are invited to visit Albis Optoelectronics’ booth #1657 to discover how our photodiodes can elevate optical communication systems to new heights.
Yokogawa T&M new optical spectrum analyser
Yokogawa Test & Measurement Corporation has released the AQ6377E optical spectrum analyser for mid-wave infrared (MWIR) measurements. The AQ6377E offers a number of new features and functions over the previous AQ6377 model that enhance speed, accuracy, and capability, enabling it to meet a broader spread of laser application demands, including environmental measurement. As the successor model to the AQ6377, the AQ6377E optical spectrum analyser presents users with a number of new functions and specifications. For instance, the AQ6377E offers improved performance of the built-in chopper, a device that modulates light by periodically interrupting light
Yokogawa says the AQ6377E also offers much wider pulsed light measurement capabilities thanks to the addition of a new function, ‘advanced pulsed light measurement mode’. This enhancement provides engineers with improved ability to measure pulsed light with low-repetition frequencies that were previously impossible to achieve using the AQ6377. In laser evaluation, simultaneous measurement over a wide level range was a clear performance advantage of the previous AQ6377. The new AQ6377E adds to this with a dynamic measurement range for the simultaneous measurement of a laser’s optical spectrum. This improvement ensures engineers can accurately evaluate the SMSR, an index of laser performance, which is difficult to achieve with an FT-OSA.
rays with a vane that rotates at a constant speed, which operates automatically according to the measurement sensitivity setting. Specifically, Yokogawa has added the NORMAL/CHOP and MID/CHOP measurement sensitivity settings, which apply the lock-in detection function to
the intermediate NORMAL and MID sensitivities of the previous model. This capability reduces the impact of background noise when measuring MWIR light spectra and allows faster and more accurate measurement compared with the previous AQ6377.
