Alain Haché (born 1970) is an experimental physicist, a professor at the University of Moncton, Canada.[1] From 2003 to 2013 he held the Canada Research Chair in photonics.[2] He is also the author of The Physics of Hockey [3] and Slap Shot Science,[4] two popular science books on ice hockey.
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.
