Abstract
A thin‐film lenslike light guide was made by rf sputtering of one glass film on another glass substrate. The one‐dimensional focusing properties which depend upon the propagating mode are to be demonstrated. A basic theoretical treatment is given which shows that the focusing power increases with the mode number. The focusing parameters were determined experimentally. The over‐all experimental results were in good agreement with the theoretical predictions.Keywords
