Haché was born in Tracadie, New Brunswick in 1970.[citation needed] In 2002, he and undergraduate student Louis Poirier transmitted faster-than-light electrical pulses through a 120-metre long "photonic crystal" made of coaxial cables of alternating characteristic impedance (12 pairs of 50 Ω and 75 Ω cables).[5][6] The experiment showed that the pulse envelope was recreated at the end of the cables at a speed of >3 c. This speed represents the group velocity, but the amplitude of the signal also drops in such a way that the energy transmitted never exceeds, at any given time, the energy that would have been transmitted by same pulse travelling in a vacuum.
