The subject of this dissertation is to use precision cutting and polishing techniques to fabricate thin-film filters(TFFs) with a thickness of less than 100 £gm, and to discuss their applications in Wavelength Division Multiplexing(WDM) systems. To demonstrate the feasibility of the proposed technology, Si benches with wet-etching V grooves for precision fiber positioning and saw-cutting U grooves for placing the TFFs were fabricated. The insertion loss of the bench at 1.55 £gm input lights is less than - 0.5 dB.
In addition, the stress induced pass band variations of band-pass TFF for Coarse WDM(CWDM) applications were studied. The pass band width of the band-pass TFF is 20 nm. After reducing the thickness of the 1.5 mm ¡Ñ 1.5 mm BP TFF to a thickness of 50 £gm, the center wavelength shift and pass band reduction are 4.64 nm and 1.54 nm, respectively.
