Abstract

Colloidal PbS and PbSe quantum dots are mixed with polystyrene and spincoated on top of a silicon-on-insulator microring notch filter. We demonstrate that the light propagating through the ring resonator strongly interacts with the quantum-dot doped thin film. This allows us to efficiently tune the output of the notch filter by varying the quantum-dot size and concentration. As a result, the hybrid devices can exhibit critical coupling only for a single resonance or display a constant extinction ratio over a wide spectral range. Considering the promising nonlinear optical properties of colloidal quantum dots, our results open new pathways for all-optical signal processing applications on a silicon platform.

Figures (7)

Fig. 1
Fig. 1

Typical series of absorbance spectra for (a) PbSe and (b) PbS nanocrystals. The absorption peaks shift to shorter wavelengths as the particle size decreases.

Fig. 2
Fig. 2

Absorbance spectra for undoped (transparent) PS and Q-PbSe doped PS thin films with varying Q-PbSe volume fraction f spin-coated on a glass substrate. Interference fringes are observed for pure PS and the Qdot doped thin films with f = 1 % and 2%. For f = 5 % , a tail extending to long wavelengths indicates that scattering losses are not negligible at this volume fraction. The absorbance spectrum of the Q-PbSe suspended in C 2 Cl 4 is shown for comparison (top trace). All spectra are offset for clarity.

Simulation of the optical mode profile of a wire with a width of 450 nm and a height of 220 nm . The mode expands 50 60 nm into the PS cladding on top and the oxide underneath.

Fig. 5
Fig. 5

(a) Transmission spectra of a notch filter coated with pure PS and Q-PbSe doped PS. (b) Resulting loss per round trip a and transmission t. A strong decrease of a is observed after doping, while t is unaffected by the presence of the Q-PbSe. (c) The Q-factor is strongly reduced after incorporation of the nanocrystals due to the decrease in a.

Fig. 6
Fig. 6

(a) The absorption coefficient α of samples 1 (○), 2 (◇), and 3 (△) shows an excellent correlation with the Q-PbSe absorbance spectrum. (b) By increasing the Q-PbS volume fraction in the PS film, the resonance shifts to longer wavelengths. (c) The Q-factor also decreases. This is due to a decrease in a, as t remains fairly constant.

Fig. 7
Fig. 7

Transmission spectrum of a notch filter coated with a Q-PbSe doped PS film (sample 3). A constant extinction ratio of 4.84 dB is observed over a 120 nm wavelength range.
