RT Book, Section T1 Advanced concepts in waveguide spectrometers A1 Martínez Matos, Óscar A1 Cheben, Pavel A1 Schmid, Jens H. A1 Bogdanov, Alexei L. A1 Calvo Padilla, María Luisa A1 Delâge, André A1 Densmore, Adam A1 Janz, Siegfried A1 Lamontagne, Boris A1 Lapointe, Jean A1 Post, Edith A1 Powell, Ian A1 Rodrigo Martín-Romo, José Augusto A1 Waldron, Phillip A1 Xu, Dan-Xia AB We present several new concepts to extend the capabilities of arrayed waveguide grating spectrometers. Strong lateral mode confinement wavegaide structure in the focal plane is used to increase resolution, a Michelson-type AWG spectrometer can improve optical throughput or etendue, and we show that AWG dispersion can be magnified many times by modifying the waveguide group index.
