In　this　thesis,　the　author　proposed　a　simple　approach　to　fabricating　2-D　holographic　photonic　crystal　with　large　band-gaps,　and　have　discussed　the　factors　that　influence　on　broadening　the　band-gaps.　It　was　found　that　a　unexpected　diffracted　peak　is　always　accompany　the　designed　and　expected　peaks.　Also,　one　of　the　expected　peaks　will　disappear　if　incident　angle　during　recording　is　larger　than　a　critical　value.　On　the　other　hand　,　the　extra　diffraction　peak　will　enlarge　the　band-gap　if　incident　angle　is　less　than　a　certain　value,　but　when　angle　is　larger　than　the　certain　value,　one　of　the　expected　main　peaks　will　disappear,　and　the　band-gap　will　get　narrow　instead.　This　phenomenon　is　guidable　for　fabrication　of　2-D　holographic　photonic　crystals　with　broadened　band-gap.
