PDM laser sources - Pulse-on-demand Modules

The PDM+ laser sources are specially designed for security evaluation of integrated circuits. Reliable and robust, these laser sources are all fibered design lasers with field proven excellent reliability.

The PDM+ laser sources allow the generation of on-demand pulses ranging from 1 ns pulse duration, with a jitter below 20 ps (standard deviation) on the trigger to pulse delay and a spot size down to 1 µm diameter (x50 objective).

The PDM+ lasers enable a wide range of peak power (2 to 10 W) for your applications and can easily be used in laser fault injection even through thicker silicon dies

Temporal agility

The principle of the PDM+ (Pulse-on-Demand Module) laser sources is to be able to generate the optical pulse request via an external triggering signal or an internal pulse generator.

These sources provide the required timing precision for fault injection on integrated circuits. Typically, the PDM+ laser sources enable:

trigger input: TTL/LVTTL digital signals
variable pulses going from one nanosecond to continuous wave
from single pulse shot up to 250 MHz
timing precision on arrival of pulse <20ps Std Dev

The laser sources can be driven by analog signal or by computer with dedicated software or hexa commands.

A wide range of PDM laser sources adapted to your projects

ALPhANOV offers different types of PDM Laser sources:

The PDM HPP - High Pulse performance, ideal for ultra-short pulses up to 2 W peak power.
The PDM2 HPP, combining two PDM HPP modules into one output fiber, up to 3.6 W peak power.
The PDM+ & PDM+ HP generating pulses up to 3.2 W peak power.
The PDM2+ & PDM2+ HP combining two PDM+ modules into one output fiber, up to 5 W peak power.
The PDM4+ & PDM4+ HP combining four PDM+ modules into one output fiber, up to 10 W peak power.

PDM2+ Design

PDM High Pulse Performance

The PDM HPP (High Pulse Performance) reaches its power 5 times faster than traditional PDM+. This source is ideal for ensuring there is enough power for injecting faults with very short pulse duration
(<2 ns) and for more effectively assessing the safety of increasingly fast components (<2 ns).

The PDM HPP enables faster rise time than the classic PDM+ version. Even at <2 ns pulse duration, enough electron-hole pairs can be created to induce faults in integrated circuits.

PDM HPP VS PDM+

Features

Single-shot, burst mode or CW operation
Up to 250 MHz repetition rate
Up to 3.2 W peak power
Delay trigger to pulse :
typ 30 ns (Ext/Ext mode, PDM module only)(1)
typ 100 ns (PDM in Ext/Ext mode, Tombak included)
Low jitter <20 ps (Std Dev) vs trigger

Python compatible

(1)«Ext/Ext mode» : the laser uses the external signal for repetition rate and pulse duration.
A so-called «Ext/Int mode» enables the user to use the external signal for the repetition rate and to configure the pulse duration via the software interface. In that case, the total delay is typ. 70 ns.
