Photonic crystal notch filter plays a vital role in photonics applications which can selectively attenuate the unwanted interference. However， it remains challenging to achieve high efficiency and is generally limited to the single notch performance. Here， we demonstrated a high efficient all-silicon multi-notch filter scheme utilizing photonic crystal nanorod flower-shaped resonators. Based on the single resonant cavity， the dielectric columns can be introduced to create the intracavity asymmetry achieving double notch， meanwhile by adding the certain scattering nanorods to trap light efficiently， it can also obtain triple notch. The results emanate that the transmission and the Q of single notch up to 2.6% and 16209.4， double notch 0.5%， 0.1% and 12371.7，13934.5， triple notch 0.2%， 0.5%， 2.3%， 2312.9， 2062.8， 2327.4 can be achieved， respectively. The proposed high efficient multi-notch filters could potentially catalyze advancements in filter technology within the realm of silicon photonics applications and optical communication.

以十七氟癸基三乙氧基硅烷和乙醇分别作为修饰剂和溶剂,通过后接枝法将十七氟癸基修饰到γ/α-Al_2O_3多孔陶瓷膜表面,对碳氟基团修饰的γ/α-Al_2O_3多孔陶瓷膜表面形貌、化学组成、亲/疏水性进行表征,并考察接枝的碳氟基团对其表面自由能和气体/纯水渗透性能的影响.结果表明,碳氟基团的引入极大地降低了γ/α-Al_2O_3多孔陶瓷膜的表面自由能,使其表面发生从亲水到疏水的转变.接枝到γ/α-Al_2O_3多孔陶瓷膜孔道的碳氟基团一定程度上增加了气阻,使得气体渗透率略有下降,气体分子在孔道内的输运遵循Knudsen扩散机制.压差0.35 MPa条件下,纯水不能透过修饰后的α-Al_2O_3以及修饰后的γ/α-Al_2O_3多孔陶瓷膜.
