Angle-spliced SMF to hollow core fiber connection with optimized back-reflection and insertion loss


Uploaded Archive (RAR) includes 5 data files that are Excel format (.xlsx)


The figures are as follows:

 
Fig. 1:	Relationship between GRIN angle (Column A) and back-reflection (Column C).
		
Fig. 2: 	GRIN angle (column A) versus Connection loss. Column B are theoretically predicted connection loss value (for singe SMF-GRIN-HCF side connection) 
                under different angles. Column C are experimental connection loss results (one side) under 0.1, 1.1 and 2.2 degree.

Fig. 5: 	Differential group delay (DGD) (Column A) calculated by Fourier transformation of the transmission spectra under different angle connection (0.1 degree, column B; 
                1.1 degree, column C; 2.2 degree, column D)

Fig. 6: 	OTDR measurement of three samples with average angles of 0.1°, 1.1°, and 2.2° degrees. Column A is the length of fiber link; Column B is the reflection power value
                of 0.1 degree connection link; column C is the reflection power value of 1.1 degree connection link; column D  is the reflection power value of 2.2 degree connection link;

Fig. 7:	BER measurement of different angle connection link. Column A is the received power. Column B is the -log(BER) value of back-to-back link; Column C is the -log(BER) 
                value of 0.1 degree HCF connection link. Column D is the -log(BER) value of 1.1 degree HCF connection link. Column E is the -log(BER) value of 2.2 degree HCF connection link
