"could be a game-changer for communication technologies, such as phones and internet connections... converts light oscillations into electrical signals, much like hospital monitors convert a patient’s heartbeat into electrical oscillation... speed of the oscilloscope... Our optical oscilloscope may be able to increase that speed by a factor of about 10,000... developed the device and demonstrated its capability for real-time measurement of the electric fields of individual laser pulses"
