Fallback disks are a general prediction of core-collapse supernova models, yet there are few observational constraints on the size (or existence) of these disks. If they exist, these disks could significantly affect the evolution of pulsars and could even lead some new-born neutron stars to collapse into black holes. Theory predicts that fallback disks around young neutron stars should be optical/IR emitters due to irradiation by the central X-ray source. The radio-quiet, compact X-ray point sources detected near the centers of several core-collapse supernova remnants offer a good opportunity to make a sensitive search for such optical/IR emission, since they are uncontaminated by nonthermal pulsar emission. We will report on our ground-based optical and infrared search of these targets for fallback disk emission.
