1. Use square wave for minimal additive jitter, particularly at repetition below 100MHz. 2. Repetition rate can be tuned by tuning the input clock frequency. Max. repetition rate is limited by pulse width. Please inquire for operation at <1MHz. The device can also be triggered on-demand within the specified frequency range. 3. Custom pulse width up to 2.5ns is possible. The pulse width is fixed at a user-selected value, and is set at factory. This represents the minimum pulse width when combined with tunable pulse width option. The pulse width may broaden when combined with the high-voltage option (e.g. for 30ps model, the pulses may broaden to up to 35ps). 4. Voltage for single-ended output. 5. Available for single-ended output only. Rise/fall times, and hence pulse width, may increase by a few ps. The output voltage may vary with pulse repetition rate. 6. When driven at >1GHz. Actual jitter depends on clock/trigger source. 7. Module type is possible for fixed pulse widths of 30, 50, 75 or 100ps, and with standard output voltage. The above specifications may change without prior notice.
Typical Performance
The EPG-210 is a versatile solution for generating <100ps optical pulses, either by driving LN modulators or driving gain-switched lasers. In particular: Electrical pulse width as short as 30ps, with option to add 200ps tunability. Fast rise / fall time of 17ps, and low additive jitter. Repetition rate can be tuned from 5GHz to 1MHz, and in principle to single-shot, simply by tuning the input clock / trigger. Much more cost-effective than expensive 40Gbps pulse pattern generators.
Driving a LN Modulator
Optical Pulses with Fast Rise-Time
The EPG-210 generates electrical pulses with fixed, fast rise/fall time of 17ps (for pulse width >50ps). By driving LN modulators with the EPG-210, optical pulses with similarly fast rise/fall times of ~17ps can be generated.
Driving a Gain-Switched Laser
Low-Jitter
The EPG-210 can be used to gain-switched lasers to generate 30-60ps optical pulses. The 18ps fast rise-time of the driver electrical pulse helps to suppress timing jitter.
EPG-210 as a RF Comb Source
The EPG-210 can also be applied as a RF comb source. The output pulses have high-speed RF components that span to over 25GHz, while the frequency-spacing of the comb lines can be adjusted by tuning the pulse repetition rate. Applications include characterization of RF antennas.
