FIBER OPTIC SERIES
UDT Sensors offers a variety of fiber optic detectors. They include:
Fiber Optic Series-Silicon: are several families of small active area sili-
con photodiodes divided into High Responsivity Series (HR), High Speed
Series (HS) and Ultra High Speed (UHS) series.
Fiber Optic Series-Silicon / Hybrid: is a 90 MHz integrated silicon pho-
todetector / transimpedance amplifier hybrid with a single power supply
and linear differential output voltage for applications such as Ethernet
and token ring systems. This detector is available with a micro lens cap.
Fiber Optic Series-Silicon APD: is a small active area Silicon A valanche
Photodiode with gains up to a few hundred with a typical reverse bias of
• Fiber Optic Communication Links • Speeds in sub ns
• V ideo Systems • High gain
• Laser Monitoring Systems • Low dark current
• Computers and Peripherals • Low capacitance
• Industrial Controls • TO-46 metal can
• Guidance Systems With lensed cap
• FDDI Local Area Networks
• High Speed Optical Communications
APPLICATIONS FEATURES
only 325 V. It provides high gain bandwidth product and high responsivity
compared to detector/transimpedance amplifier combination.
Fiber Optic Series-Silicon BPX-65: is a 1 x 1 mm active area high speed
silicon photodetector for high modulation bandwidth applications where
a large active area is needed.
Fiber Optic Series-InGaAs: devices are high speed InGaAs detectors ex-
hibiting a spectral range of 850 to 1700 nm. These detectors are specifi-
cally designed for NIR optical communication, providing high responsivity ,
low capacitance and high speed. They are available with micro lens cap.
All of the above detectors and /or hybrids ar e also available with a spherical micro lens cap to enhance fiber optic coupling efficiency. They can also
be provided with any of the standard r eceptacles such as SMA, ST, FC, etc., for direct optical fiber coupling.

HIGH SPEED SILICON SERIES
FIBER OPTIC PHOTODIODES
UDT Sensors Silicon Fiber Optic detector series consist of three families of
small active area photodiodes with High Responsivity (HR Series), High Speed
(HS Series) and Ultra High Speed (UHS Series) properties.
The spectral range for these devices are from 350 nm to 1100 nm. The
responsivity and response time are optimized such that the HR series exhibit a
peak responsivity of 0.50 A/W at 800 nm and typical response times of a few
hundred pico seconds at -5V, while the HS series have a peak responsivity of
0.40 A/W at 750 nm and typical response times less than 500 ps at -3V.
• Fiber Optic Communication Links • Sub ns Response
• V ideo Systems • Low Dark Current
• Computers and Peripherals • Low Capacitance
• Industrial Control • TO-46 Package
• Guidance Systems • w/ FO Receptacle
• Laser Monitoring • w/ Lensed Cap
APPLICATIONS FEATURES
UDT Sensors' Ultra High Speed (UHS) detector demonstrates state of the art
detector technology , achieving response times less than 300ps at -3V reverse
bias.
Note that for all high-speed photodetectors, a reverse bias is required to achieve
the fastest response times. However, the reverse bias should be limited to
maximum reverse voltage specified to avoid damage to the detector. Output
signals can be measured directly with an oscilloscope or coupled to high fre-
quency amplifiers as shown in figure 10 of the Photodiode Characteristics sec-
tion of the catalog.
