  We report initial results from the detection of optical emission in the
arcsecond-scale radio jets of two quasars utilizing images from the {\it Hubble
Space Telescope} archive. The optical emission has a very knotty appearance and
is consistent with synchrotron emission from highly relativistic electrons in
the jet. Combining these observations with those of previously reported
features in other quasars, an emerging trend appears to be that their
radio-to-optical spectral indices are steeper than those of similar features in
jets of lower power radio sources.
