it can be significantly influented by environment We consider the resonance energy transfer rate of atoms positioned inside of a multilayered-cylindrical waveguide The configuration studied is a Bragg-distributed mirror type The dependence of resonance energy transfer on the distance of the atoms-surface as well as the frequency dependence of the emitted photon will be considered The results show that the amplification or annihilation is very strong when the Bragg coditions are satisfied Keywords Bragg-distributed mirror, Cylindrical waveguide, Resonance energy transfer T (RET) RET RET có g thơng qua photon, V R T R [2] nh [4 © 2020 Thành 91 6] 7] t ó mode (2018) [8] nguyên nguyên S n c a v t ch t tán s c h p th b t k th trình sau [9] (1) H (r ) hai (r , ) c2 (r , ) (2) chi 6] W W0 | d DG (rD , rA , )d A |2 | d DG0 (rD , rA , )d A |2 (3) rA , rD W0 dA l thái u K © 2020 Thành 92 dj Re , j( ) ( j ) , (4) 2.1 K hàm vector sóng M e on f N e ngồi G (11) (r , r , ) A Khi on f hàm Green i n (2 dh ) C111H M o(1)n (h) M e (1) ( h) n e n o C111H N o(1)n (h) N e (1) ( h) C211H N o(1)n (h)M e (1) ( h) C211V M o(1)n (h) N e (1) ( h) n n n e K o e o e o (5) rong i G ( NN ) (r , r , ) n (2 dh n ) (1) (1) C3NN H M o n ( h) M e n ( h) e N o N (1) (1) NN (1) (1) NN (1) (1) C3NN V N o n ( h) N e n ( h) C4 H N o n (h) M e n ( h) C4V M o n (h) N e n ( h) e N o N e N o N e N o N (6) A6) (A7) A9) C1(11H ,V ) T12( H ,V )T23( H ,V ) T13( H ,V )T22( H ,V ) T11( H ,V )T22( H ,V ) T12( H ,V )T21( H ,V ) 11 C2( H ,V ) T13( H ,V )T21( H ,V ) T11( H ,V )T23( H ,V ) T11( H ,V )T22( H ,V ) T12( H ,V )T21( H ,V ) NN 3( H ,V ) T31( H ,V )T22( H ,V ) T32( H ,V )T21( H ,V ) T11( H ,V )T22( H ,V ) T12( H ,V )T21( H ,V ) C (7) T41( H ,V )T22( H ,V ) T42( H ,V )T21( H ,V ) T11( H ,V )T22( H ,V ) T12( H ,V )T21( H ,V ) [Tij( k )( H ,V ) ]4 x TN( H1,V )TN( H2,V ) Tk( H1 ,V )Tk( H ,V ) C4(NNH ,V ) (8) H L , xen k ng N (khơng trình bày 3.1 Chúng tơi gi s ng t o nên kh i tr dày h u h n c t o nên b i l p Si/SiO2 xen k v ih s ng , ng c a bu ng c ng có kh n x t t Tuy nhiên, v n cho phép m ng h u h n photon ngồi © 2020 Thành 93 Hình 2: T D A d 0,1 - d g d - -b - Si / SiO2 xen k Trên hình 2, g cách g - xanh, g - nguyên g g cách xa [7] Các g g mode W W W g - - g N r , g cách - hác, © 2020 Thành 94 W C ) g A A /3 - - A d /6 - Trên hình 3, mơi C g / 6, A / , A - - © 2020 - Thành A /6 /3- 95 3.2 D A d 0,1 - d 0 g d - - Si / SiO2 xen k Trên hình 4, u g - bé, - kh © 2020 Thành 96 g A A /3 - A d - g /6 - Trên hình 5, - A / 6- ln theo K chân không H N (s 1, 2, , N ) © 2020 (f Thành 1,2, , N ) 97 r G fs r r G( f 1) s , G fs f (A1) r G( f 1) s , (A2) f G fs G0e Gesfs G fs (r, r ) G0e (r, r ) s f Gesfs (r, r ) (A3) Hàm Green không biên G0e rr (r r' ) G0e (r, r' ) i k s2 M (1) ( h) M' e e on s on s Me on s Gesfs (r, r' ) i s n ( h) N (1) (h)N' e e on s on s (h) (1 fs s )C1H M e n (1 (1) N f )N e on f (h) (1 fs s )C1V N e n (1 (1) N f )N o en f (h) (1 fs s )C2 H M e n s (1 (1) N f )M o en f (h) (1 fs s )C2V N e n s (1 f )M e n ( h) (1 fs s )C3 H M e n s (1 f )N e n f (h) (1 fs s )C3V N e n (1 f )N o n f (h) (1 fs s )C4 H M e n s (1 f )M o n ( h) (1 fs s )C4V N e n s o o e e f f r' (h)N' e(1) ( h) r r' on s o o ( h) (1 s o o o o o o ( h) (1 s s fs N (1) s )C'1H M e n o fs (1) N s )C'1V N e n o s ( h) fs N (1) s )C' H M e n ( h) (1 fs N (1) s )C' 2V N e n ( h) (1 fs N (1) s )C'3 H M e n ( h) (1 o o s o fs N (1) s )C'3V N e n o s fs N (1) s )C' H M e n ( h) (1 fs N (1) s )C'4V N e n o N s ( h) ( h) s ( h) ( h) ( h) (1 o ( h) s ( h) (1 f C1fsH , C1Vfs (A4) s (1) N f )M e on f (1 r n) (2 n ( h) on s on s (h)M' e(1) ( h) N e dh n) (2 dh s s ( h) ( h) , N s A1) (A2 A5) M e on f N e on f i [11] © 2020 Thành (A5) 98 M (1) e on f Z n(1) ( j rA )sicons (n )eihz z ( h) nZ n(1) ( j rA ) sin cos ( n r N (1) e ( h) on f h h sin ( n r n 2f )r )r e , (1) cos f Z n ( j rA )sin (n )z eihz Z n(1) ( j rA ) Z n(1) ( j rA ) k 2f k 2f f f f kf f h2 ) (A7) ihn (1) Z n ( j rA )sin cos (n ) r A6) (A7 f sin (n r ihz cos Z n(1) ( j rA )sin (n )eihz z n 2f Z n(1) ( j rA ) cos 2 (A6) Z n(1) ( j rA ) cos , f (A8) , f f C (A5 V , (A9) C H ,V C fs N f 1 s C1fsH ,V N f N s C'1fsH ,V N f 1 s C2fsH ,V N f N s C'2fsH ,V 1 f 1 s C3fsH ,V 1 f N s C'3fsH ,V 1 f 1 s C4fsH ,V 1 f N s C'4fsH ,V A1 © 2020 0 0 0 Thành ;
