Photoluminescence at 1.53 um from Er: SiN x on silicon photonic crystal cavities was extracted via fiber tapers with 2.5 x greater collection efficiency compared to free space emission. Fibers were also used to demonstrate a 10 nm tuning range of 750 nm SHG emission from GaP cavities.

A silicon microsphere coupled to a silica optical fiber half coupler is excited using a diode laser operating at 1.55 mu m. The transmitted and the 90 degrees elastically scattered light signals are modulated with an electrical square wave applied to the silicon microsphere.

We demonstrated enhancement of light emission from Er-doped silicon photonic crystal cavities, as well as cavity linewidth narrowing with increasing optical pump power at low temperature-an indication of differential gain in the system.
Optical Modulation With Silicon Microspheres
Yüce, Emre; Serpenguzel, Ali (Institute of Electrical and Electronics Engineers (IEEE), 2009-10-15)
In this letter, a silicon microsphere coupled to a silica optical fiber half coupler has been characterized for electrooptical modulation in the L-band at 1.55 mu m. Electrooptical modulation of the transmitted and the 90 degrees elastic scattered signals for both the TE and the TM polarizations of the microsphere resonances has been observed.

Photoluminescence at 1.54 μm from Er-doped silicon nitride embedded in silicon photonic crystal cavities was extracted with 2.5× greater collection efficiency compared to free space emission, with loaded Q values of up to 98% of the intrinsic Q.
Intrinsic photoconductivity of P3HT films measured by time-resolved THz spectroscopy
Esentürk, Okan; Heilweil, Edwin J. (2007-12-01)
Intrinsic photoconductivities of P3HT polymers were measured and compared by using optical pump-THz probe spectroscopy. The charge carrier mobility shows a clear dependence on the molecular weight and dispersion index of the polymers.
