  • Two degrees-of-freedom Lloyd-Mirror interferometer for superior pattern coverage area.
    Optics letters, 2011
    Co-Authors: Ishan Wathuthanthri, Weidong Mao, Chang-hwan Choi
    Abstract:

    In this study, we have developed a tunable Lloyd-Mirror interferometer with two degrees of freedom, in contrast to a traditional system with one degree of freedom. This new Lloyd-Mirror interferometer allows an angular rotation of the Mirror independently from that of a sample stage, resulting in an increased pattern coverage area with tunable pattern periodicity. Both theoretical and experimental results verify that the tunable characteristic of the modified configuration enhances the nanopatterning capabilities of the Lloyd-Mirror interference lithography system especially in achieving greater pattern coverage area for larger pattern periodicities.

  • Tunable Lloyd-Mirror Interferometer for Large-Area Nanopatterning
    Volume 12: Micro and Nano Systems Parts A and B, 2009
    Co-Authors: Ishan Wathuthanthri, Chang-hwan Choi
    Abstract:

    This paper reports on a new Lloyd-Mirror interference lithography system whose Mirror angle is variable with respect to the substrate. We demonstrate that this tunable Lloyd-Mirror interferometer significantly increases the nanopatterning area with greater controllability compared to a conventional fixed-angle system for pattern periodicity over 500 nm. The new configuration capable of the independent control of Mirror angle will enhance the advantages of Lloyd-Mirror interferometer for large-area nanopatterning with more flexibility.Copyright © 2009 by ASME

    Abstract:

    Telah dilakukan fabrikasi kristal fotonik satu dimensi (1D)dari bahan polimer hibrid, untuk diaplikasikan sebagaibiosensor optik. Bahan polimer hibrid diperoleh secarasintesis dari 3-(Trimethoxysilyl)propyl methacrylate(TMSPMA) dengan metode sol-gel. Untuk mengaktifkansifat lasingnya, prekursor polimer hibrid dimodifikasidengan kromofor (4-dicyanmethylene-2-methyl-6-(p-dimethylaminostyryl)-4H-Pyran (DCM) melalui metode guesthost.Selanjutnya dilakukan fabrikasi kristal fotonik 1Ddengan teknik interferensi Lloyd Mirror. Hasil pengujianmenunjukkan bahwa polimer hibrid dapat bersatu secarahomogen dengan kromofor DCM. Polimer hibrid dapatberubah fasa dari gel menjadi padat apabila disinari dengancahaya UV. Fabrikasi kristal fotonik 1D dapat dilakukandengan menggunakan berkas cahaya terpola, yangdihasilkan dari metode interferensi Lloyd Mirror. Metodetersebut telah diketahui cukup baik untuk memfabrikasikristal fotonik 1D dengan beragam periode kisi

  • Fabrikasi dan Karakterisasi Kristal Fotonik Satu Dimensi untuk Aplikasi Divais Laser Planar
    'Universitas Padjadjaran', 2012
    Co-Authors: Hidayat Sahrul
    Abstract:

    Fabrication of 1D photonic crystal using hybrid polymer for planar laser application has been carried out. The hybrid polymer material was synthesized by sol-gel route using 3-(Trimethoxysilyl) propyl methacrylate (TMSPMA) as monomer. Then, the hybrid polymer is modified with (4-dicyanmethylene-2-methyl-6-(p-dimethyl-aminostyryl)-4H-Pyran (DCM) by guest-host method. Fabrications of 1D photonic crystal have been conducted by Lloyd Mirror interference method. The results of characterization show that organic-dye (DCM) good incorporated with hybrid polymer in sub-micrometer scale. The hybrid polymer can change from gel into solid by irradiated using UV-light. The Lloyd Mirror interference method was used to make light patterns in sub-micrometer order for fabrication of 1D photonic crystal. We found it method is quite well for fabrication of 1D photonic crystal with various periods.******Telah dilakukan fabrikasi kristal fotonik satu dimensi (1D) dari bahan polimer hibrid, untuk diaplikasikan sebagai divais laser planar. Bahan polimer hibrid diperoleh secara sintesis dari 3-(Trimethoxysilyl)propyl methacrylate (TMSPMA) dengan metode sol-gel. Untuk mengaktifkan sifat lasingnya, prekursor polimer hibrid dimodifikasi dengan kromofor (4-dicyanmethylene-2-methyl-6-(p-dimethyl-aminostyryl)-4H-Pyran (DCM) melalui metode guest-host. Selanjutnya dilakukan fabrikasi kristal fotonik 1D dengan teknik interferensi Lloyd Mirror. Hasil pengujian menunjukkan bahwa polimer hibrid dapat bersatu secara homogen dengan kromofor DCM. Polimer hibrid dapat berubah fasa dari gel menjadi padat apabila disinari dengan cahaya UV. Fabrikasi kristal fotonik 1D dapat dilakukan dengan menggunakan berkas cahaya terpola, yang dihasilkan dari metode interferensi Lloyd Mirror. Metode tersebut telah diketahui cukup baik untuk memfabrikasi kristal fotonik 1D dengan beragam periode kisi
