We study the interaction of a co-propagating finite energy Airy pulse and a\nsoliton in a Kerr medium under third order dispersion. It is observed that a\nstrong radiation appears when selfaccelerating Airy pulse collides with a\ndelayed soliton in time domain. We confirm both analytically and numerically\nthat this radiation can only be initiated in the environment of third order\ndispersion (TOD). The radiation frequency is red or blue shifted depending on\nthe numeric sign of TOD parameter. We adopt a simple Si-based waveguide to\nvalidate the normalised parameter that we use for the analysis. We develop a\ntheory to explain the collision-mediated radiation and our theoretical results\nare found to be in good agreement with the direct numerical modelling of the\ngeneralised nonlinear Schrodinger equation (GNLSE).\n
