High Sensitivity Fast PIN Photodetector Series FPD510 - Menlo Systems - #1

Text version of the page

High Sensitivity Fast PIN Photodetector Series FPD510 The high sensitivity PIN Photodetector FPD510 is optimized for highest signal-to-noise ratio when detecting low level optical beat signals at frequencies up to 250 MHz. The unit is recommended in particular for applications in metrology when beat signals of weak power have to be detected in a highly efficient way. Models for both the visible and the near infrared regime are available. Features • High signal-to-noise ratio • Flat spectral response (less than 3dB up to 200 MHz) • OEM package with FC/APC pigtail (SMF28) or free space module • Available for visible and near infrared spectral range Applications • Efficient detection of optical beat signals at frequencies up to 250 MHz • Detection of fiber coupled or freespace low light level signals • OEM integration 0 20 40 60 80 100 Frequency [MHz] -80 -70 -60 -50 -40 -30 -20 Signal [dBm] 0 50 100 150 200 250 Frequency [MHz] -80 -60 -40 -20 0 Signal [dBm] 0 10 20 30 40 50 60 70 80 90 Time [ns] 0 0.1 0.2 0.3 0.4 Signal [V] Time Characteristics FPD510: Pulse response of a femtosecond pulse train at 1560 nm Time Characteristics Frequency Characteristics Example Application: Offset Beat of Self-referenced Frequency Comb Input Signal: 250 fs Pulses @ 1560 nm average power 1.25 microW Input Signal: 250 fs Pulses @ 1560 nm average power 1.25 microW detail view 0 2 4 6 8 10 12 14 Time [ns] -0.1 0 0.1 0.2 0.3 0.4 Signal [V]
