Kristal fotonik merupakan platform ideal untuk pengembangan devais optik terintegrasi. Interaksi antara foton dengan modulasi periodik pada indeks bias mengakibatkan terbentuknya celah pita optik yang memberi peluang untuk mengontrol perambatan dan emisi cahaya serta interaksinya dengan bahan. Kristal fotonik tiga dimensi biasanya difabrikasi menggunakan teknik self-assembly karena selain murah dan mudah dilakukan, teknik ini dapat digunakan untuk membuat kristal dengan berbagai periodisitas. Opal hanya memiliki celah pita optik pada arah tertentu saja (stop band) tapi dapat dimodifikasi atau digunakan sebagai template untuk inverse opal yang memiliki celah pita optik dalam segala arah (omnidirectional). Lebar stop band dari opal dan core-shell opal akan dioptimasi dengan memvariasikan indeks bias medium dan struktur kristal. Hasil simulasi menunjukkan bahwa opal dengan partikel tidak saling bersentuhan memiliki stop band terlebar dan memiliki potensi untuk digunakan sebagai devais optik.
